Mishka got an integer array $$$a$$$ of length $$$n$$$ as a birthday present (what a surprise!).Mishka doesn't like this present and wants to change it somehow. He has invented an algorithm and called it "Mishka's Adjacent Replacements Algorithm". This algorithm can be represented as a sequence of steps: Replace each occurrence of $$$1$$$ in the array $$$a$$$ with $$$2$$$; Replace each occurrence of $$$2$$$ in the array $$$a$$$ with $$$1$$$; Replace each occurrence of $$$3$$$ in the array $$$a$$$ with $$$4$$$; Replace each occurrence of $$$4$$$ in the array $$$a$$$ with $$$3$$$; Replace each occurrence of $$$5$$$ in the array $$$a$$$ with $$$6$$$; Replace each occurrence of $$$6$$$ in the array $$$a$$$ with $$$5$$$; $$$\dots$$$ Replace each occurrence of $$$10^9 - 1$$$ in the array $$$a$$$ with $$$10^9$$$; Replace each occurrence of $$$10^9$$$ in the array $$$a$$$ with $$$10^9 - 1$$$. Note that the dots in the middle of this algorithm mean that Mishka applies these replacements for each pair of adjacent integers ($$$2i - 1, 2i$$$) for each $$$i \in\{1, 2, \ldots, 5 \cdot 10^8\}$$$ as described above.For example, for the array $$$a = [1, 2, 4, 5, 10]$$$, the following sequence of arrays represents the algorithm: $$$[1, 2, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$1$$$ with $$$2$$$) $$$\rightarrow$$$ $$$[2, 2, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$2$$$ with $$$1$$$) $$$\rightarrow$$$ $$$[1, 1, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$3$$$ with $$$4$$$) $$$\rightarrow$$$ $$$[1, 1, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$4$$$ with $$$3$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$5$$$ with $$$6$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 6, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$6$$$ with $$$5$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ $$$\dots$$$ $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$10$$$ with $$$9$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 9]$$$. The later steps of the algorithm do not change the array.Mishka is very lazy and he doesn't want to apply these changes by himself. But he is very interested in their result. Help him find it.
Print $$$n$$$ integers — $$$b_1, b_2, \dots, b_n$$$, where $$$b_i$$$ is the final value of the $$$i$$$-th element of the array after applying "Mishka's Adjacent Replacements Algorithm" to the array $$$a$$$. Note that you cannot change the order of elements in the array.

Mishka got an integer array $$$a$$$ of length $$$n$$$ as a birthday present (what a surprise!).Mishka doesn't like this present and wants to change it somehow.

Note that the dots in the middle of this algorithm mean that Mishka applies these replacements for each pair of adjacent integers ($$$2i - 1, 2i$$$) for each $$$i \in\{1, 2, \ldots, 5 \cdot 10^8\}$$$ as described above.For example, for the array $$$a = [1, 2, 4, 5, 10]$$$, the following sequence of arrays represents the algorithm: $$$[1, 2, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$1$$$ with $$$2$$$) $$$\rightarrow$$$ $$$[2, 2, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$2$$$ with $$$1$$$) $$$\rightarrow$$$ $$$[1, 1, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$3$$$ with $$$4$$$) $$$\rightarrow$$$ $$$[1, 1, 4, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$4$$$ with $$$3$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$5$$$ with $$$6$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 6, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$6$$$ with $$$5$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ $$$\dots$$$ $$$\rightarrow$$$ $$$[1, 1, 3, 5, 10]$$$ $$$\rightarrow$$$ (replace all occurrences of $$$10$$$ with $$$9$$$) $$$\rightarrow$$$ $$$[1, 1, 3, 5, 9]$$$. The later steps of the algorithm do not change the array.Mishka is very lazy and he doesn't want to apply these changes by himself. But he is very interested in their result. Help him find it.
Print $$$n$$$ integers — $$$b_1, b_2, \dots, b_n$$$, where $$$b_i$$$ is the final value of the $$$i$$$-th element of the array after applying "Mishka's Adjacent Replacements Algorithm" to the array $$$a$$$. Note that you cannot change the order of elements in the array.

Mishka got an integer array $$$a$$$ of length $$$n$$$ as a birthday present (what a surprise!).Mishka doesn't like this present and wants to change it somehow.

It is guaranteed that there is at least one working hour in a day.
Print the maximal number of continuous hours during which Polycarp rests. Remember that you should consider that days go one after another endlessly and Polycarp uses the same schedule for each day.

Let $$$c$$$ be some positive integer. Let's call an array $$$a_1, a_2, \ldots, a_n$$$ of positive integers $$$c$$$-array, if for all $$$i$$$ condition $$$1 \leq a_i \leq c$$$ is satisfied. Let's call $$$c$$$-array $$$b_1, b_2, \ldots, b_k$$$ a subarray of $$$c$$$-array $$$a_1, a_2, \ldots, a_n$$$, if there exists such set of $$$k$$$ indices $$$1 \leq i_1 &lt; i_2 &lt; \ldots &lt; i_k \leq n$$$ that $$$b_j = a_{i_j}$$$ for all $$$1 \leq j \leq k$$$. Let's define density of $$$c$$$-array $$$a_1, a_2, \ldots, a_n$$$ as maximal non-negative integer $$$p$$$, such that any $$$c$$$-array, that contains $$$p$$$ numbers is a subarray of $$$a_1, a_2, \ldots, a_n$$$.You are given a number $$$c$$$ and some $$$c$$$-array $$$a_1, a_2, \ldots, a_n$$$. For all $$$0 \leq p \leq n$$$ find the number of sequences of indices $$$1 \leq i_1 &lt; i_2 &lt; \ldots &lt; i_k \leq n$$$ for all $$$1 \leq k \leq n$$$, such that density of array $$$a_{i_1}, a_{i_2}, \ldots, a_{i_k}$$$ is equal to $$$p$$$. Find these numbers by modulo $$$998\,244\,353$$$, because they can be too large.
Print $$$n + 1$$$ numbers $$$s_0, s_1, \ldots, s_n$$$. $$$s_p$$$ should be equal to the number of sequences of indices $$$1 \leq i_1 &lt; i_2 &lt; \ldots &lt; i_k \leq n$$$ for all $$$1 \leq k \leq n$$$ by modulo $$$998\,244\,353$$$, such that the density of array $$$a_{i_1}, a_{i_2}, \ldots, a_{i_k}$$$ is equal to $$$p$$$.

NoteIn the first example, it's easy to see that the density of array will always be equal to its length. There exists $$$4$$$ sequences with one index, $$$6$$$ with two indices, $$$4$$$ with three and $$$1$$$ with four.In the second example, the only sequence of indices, such that the array will have non-zero density is all indices because in other cases there won't be at least one number from $$$1$$$ to $$$3$$$ in the array, so it won't satisfy the condition of density for $$$p \geq 1$$$.

A permutation is a sequence of integers p1, p2, ..., pn, consisting of n distinct positive integers, each of them doesn't exceed n. Let's denote the i-th element of permutation p as pi. We'll call number n the size of permutation p1, p2, ..., pn.Nickolas adores permutations. He likes some permutations more than the others. He calls such permutations perfect. A perfect permutation is such permutation p that for any i (1 ≤ i ≤ n) (n is the permutation size) the following equations hold ppi = i and pi ≠ i. Nickolas asks you to print any perfect permutation of size n for the given n.
If a perfect permutation of size n doesn't exist, print a single integer -1. Otherwise print n distinct integers from 1 to n, p1, p2, ..., pn — permutation p, that is perfect. Separate printed numbers by whitespaces.

A permutation is a sequence of integers p1, p2, ..., pn, consisting of n distinct positive integers, each of them doesn't exceed n. Let's denote the i-th element of permutation p as pi. We'll call number n the size of permutation p1, p2, ..., pn.Nickolas adores permutations. He likes some permutations more than the others. He calls such permutations perfect. A perfect permutation is such permutation p that for any i (1 ≤ i ≤ n) (n is the permutation size) the following equations hold ppi = i and pi ≠ i. Nickolas asks you to print any perfect permutation of size n for the given n.
If a perfect permutation of size n doesn't exist, print a single integer -1. Otherwise print n distinct integers from 1 to n, p1, p2, ..., pn — permutation p, that is perfect. Separate printed numbers by whitespaces.

A permutation is a sequence of integers p1, p2, ..., pn, consisting of n distinct positive integers, each of them doesn't exceed n. Let's denote the i-th element of permutation p as pi. We'll call number n the size of permutation p1, p2, ..., pn.Nickolas adores permutations. He likes some permutations more than the others. He calls such permutations perfect. A perfect permutation is such permutation p that for any i (1 ≤ i ≤ n) (n is the permutation size) the following equations hold ppi = i and pi ≠ i. Nickolas asks you to print any perfect permutation of size n for the given n.
If a perfect permutation of size n doesn't exist, print a single integer -1. Otherwise print n distinct integers from 1 to n, p1, p2, ..., pn — permutation p, that is perfect. Separate printed numbers by whitespaces.

There are $$$n$$$ dormitories in Berland State University, they are numbered with integers from $$$1$$$ to $$$n$$$. Each dormitory consists of rooms, there are $$$a_i$$$ rooms in $$$i$$$-th dormitory. The rooms in $$$i$$$-th dormitory are numbered from $$$1$$$ to $$$a_i$$$.A postman delivers letters. Sometimes there is no specific dormitory and room number in it on an envelope. Instead of it only a room number among all rooms of all $$$n$$$ dormitories is written on an envelope. In this case, assume that all the rooms are numbered from $$$1$$$ to $$$a_1 + a_2 + \dots + a_n$$$ and the rooms of the first dormitory go first, the rooms of the second dormitory go after them and so on.For example, in case $$$n=2$$$, $$$a_1=3$$$ and $$$a_2=5$$$ an envelope can have any integer from $$$1$$$ to $$$8$$$ written on it. If the number $$$7$$$ is written on an envelope, it means that the letter should be delivered to the room number $$$4$$$ of the second dormitory.For each of $$$m$$$ letters by the room number among all $$$n$$$ dormitories, determine the particular dormitory and the room number in a dormitory where this letter should be delivered.
Print $$$m$$$ lines. For each letter print two integers $$$f$$$ and $$$k$$$ — the dormitory number $$$f$$$ $$$(1 \le f \le n)$$$ and the room number $$$k$$$ in this dormitory $$$(1 \le k \le a_f)$$$ to deliver the letter.

There are $$$n$$$ dormitories in Berland State University, they are numbered with integers from $$$1$$$ to $$$n$$$. Each dormitory consists of rooms, there are $$$a_i$$$ rooms in $$$i$$$-th dormitory. The rooms in $$$i$$$-th dormitory are numbered from $$$1$$$ to $$$a_i$$$.A postman delivers letters. Sometimes there is no specific dormitory and room number in it on an envelope. Instead of it only a room number among all rooms of all $$$n$$$ dormitories is written on an envelope. In this case, assume that all the rooms are numbered from $$$1$$$ to $$$a_1 + a_2 + \dots + a_n$$$ and the rooms of the first dormitory go first, the rooms of the second dormitory go after them and so on.For example, in case $$$n=2$$$, $$$a_1=3$$$ and $$$a_2=5$$$ an envelope can have any integer from $$$1$$$ to $$$8$$$ written on it. If the number $$$7$$$ is written on an envelope, it means that the letter should be delivered to the room number $$$4$$$ of the second dormitory.For each of $$$m$$$ letters by the room number among all $$$n$$$ dormitories, determine the particular dormitory and the room number in a dormitory where this letter should be delivered.
Print $$$m$$$ lines. For each letter print two integers $$$f$$$ and $$$k$$$ — the dormitory number $$$f$$$ $$$(1 \le f \le n)$$$ and the room number $$$k$$$ in this dormitory $$$(1 \le k \le a_f)$$$ to deliver the letter.
