package leetcodeDaily; //给你一个数组 towers 和一个整数 radius 。 // 数组 towers 中包含一些网络信号塔，其中 towers[i] = [xi, yi, qi] 表示第 i 个网络信号塔的坐标是 (xi, yi) 且信 //号强度参数为 qi 。所有坐标都是在 X-Y 坐标系内的 整数 坐标。两个坐标之间的距离用 欧几里得距离 计算。 // 整数 radius 表示一个塔 能到达 的 最远距离 。如果一个坐标跟塔的距离在 radius 以内，那么该塔的信号可以到达该坐标。在这个范围以外信号会很 //微弱，所以 radius 以外的距离该塔是 不能到达的 。 // 如果第 i 个塔能到达 (x, y) ，那么该塔在此处的信号为 ⌊qi / (1 + d)⌋ ，其中 d 是塔跟此坐标的距离。一个坐标的 信号强度 是所有 // 能到达 该坐标的塔的信号强度之和。 // 请你返回数组 [cx, cy] ，表示 信号强度 最大的 整数 坐标点 (cx, cy) 。如果有多个坐标网络信号一样大，请你返回字典序最小的 非负 坐标 // 注意： // 坐标 (x1, y1) 字典序比另一个坐标 (x2, y2) 小，需满足以下条件之一： // 要么 x1 < x2 ， // 要么 x1 == x2 且 y1 < y2 。 // ⌊val⌋ 表示小于等于 val 的最大整数（向下取整函数）。 // 示例 1： //输入：towers = [[1,2,5],[2,1,7],[3,1,9]], radius = 2 //输出：[2,1] //解释： //坐标 (2, 1) 信号强度之和为 13 //- 塔 (2, 1) 强度参数为 7 ，在该点强度为 ⌊7 / (1 + sqrt(0)⌋ = ⌊7⌋ = 7 //- 塔 (1, 2) 强度参数为 5 ，在该点强度为 ⌊5 / (1 + sqrt(2)⌋ = ⌊2.07⌋ = 2 //- 塔 (3, 1) 强度参数为 9 ，在该点强度为 ⌊9 / (1 + sqrt(1)⌋ = ⌊4.5⌋ = 4 //没有别的坐标有更大的信号强度。 // 示例 2： //输入：towers = [[23,11,21]], radius = 9 //输出 <SUF> //解释：由于仅存在一座信号塔，所以塔的位置信号强度最大。 // 示例 3： //输入：towers = [[1,2,13],[2,1,7],[0,1,9]], radius = 2 //输出：[1,2] //解释：坐标 (1, 2) 的信号强度最大。 public class B1620 { public static void main(String[] args) { } public int[] bestCoordinate(int[][] towers, int radius) { int max =0; int[] ans = new int[] {0,0}; for (int i = 0; i < 51; ++i) { for (int j = 0; j < 51; ++j) { int t=0; for(var e:towers){ double d = Math.sqrt((i-e[0])*(i-e[0])+(j-e[1])+(j-e[1])); if(d<=radius){ t+=Math.floor(e[2]/(1+d)); } } if(max<t){ max = t; ans = new int[]{i,j}; } } } return ans; } } class Solution { public int[] bestCoordinate(int[][] towers, int radius) { int mx = 0; int[] ans = new int[] {0, 0}; for (int i = 0; i < 51; ++i) { for (int j = 0; j < 51; ++j) { int t = 0; for (var e : towers) { double d = Math.sqrt((i - e[0]) * (i - e[0]) + (j - e[1]) * (j - e[1])); if (d <= radius) { t += Math.floor(e[2] / (1 + d)); } } if (mx < t) { mx = t; ans = new int[] {i, j}; } } } return ans; } }

/* Young Time Limit: 1000MS Memory Limit: 30000K Total Submissions: 271 Accepted: 108 Description Consider m natural numbers n1, n2, ..., nm with the property n1 >= n2 >= ... >= nm > 0. We define a Young table as an arrangement in a table of n1 + n2 + ... + nm natural numbers (bigger than 0 and any two different), so that the ith line has ni elements (1 <= i <= m) in ascending order from left to right, and the elements from the same column are in ascending order from bottom to top. An example of Young table for m = 4, n1 = 6, n2 = 4, n3 = 4, n4 = 1 is the following: 1 2 5 9 10 15 3 6 7 13 4 8 12 14 11 Given n1, n2, ..., nm determine the number of Young tables containing the elements 1, 2, ..., n1+n2+...+nm. Input The input has the stucture: on the first line is: the natural number m (1 <= m <= 20); on the second line are: the numbers n1, n2, ..., nm separated by a space (n1 <= 12). Output The output will contain the number of Young tables that can be built. Sample Input 2 3 2 Sample Output 5 Hint The five Young tables are: 1 3 5 1 2 3 1 2 4 2 4 4 5 3 5 1 3 4 1 2 5 2 5 3 4 */ /* 题意Overview： 给N(≤20)，用1到N2的數字來填N×N的矩陣。對於矩陣上格子(i,j)的數值a(i,j)，必須滿足a(i,j)<a(i−1,j)且a(i,j)<a(i,j−1)。问方案数。 题解Solution： 钩子公式秒杀之，各种神奇>_<。 对于N个格子的方案数。等于N!除以（每个格子上方和左方的格子数目＋1）的积。 */ //PKU OJ 1825 import java.math.*; import java.io.*; import java.util.*; public class Main { final static int SIZE = 240; public static void main(String args[]) { Scanner input = new Scanner(System.in); BigInteger ans; int[] s = new int[SIZE]; int[][] young = new int[SIZE][SIZE]; while(input.hasNext()) { int sum = 0; int n = input.nextInt(); for(int i=0;i<SIZE;i++) { for(int j=0;j<SIZE;j++) young[i][j]=-1; } ans = BigInteger.ONE; for(int i=0;i<n;i++) { s[i]=input.nextInt(); sum+=s[i]; young[i][s[i]-1]=0; } //hook-length formula for(int i=2;i<=sum;i++) ans=ans.multiply(new BigInteger(Integer.toString(i))); for(int i=n-1;i>=0;i--) { for(int j=s[i]-1;j>=0;j--) { //A hook length hook(x) of a box x in Young diagram Y(λ) of shape λ //is the number of boxes that are in the same row to the right of it //plus those boxes in the same column below it, young[i][j]=0; if(i!=n-1) young[i][j]+=young[i+1][j]+1; ans=ans.divide(new BigInteger(Integer.toString(young[i][j]+s[i]-j))); } } //ans=n!/MUL(hook(x)) System.out.println(ans.toString()); } } }

/* Young Time Limit: 1000MS Memory Limit: 30000K Total Submissions: 271 Accepted: 108 Description Consider m natural numbers n1, n2, ..., nm with the property n1 >= n2 >= ... >= nm > 0. We define a Young table as an arrangement in a table of n1 + n2 + ... + nm natural numbers (bigger than 0 and any two different), so that the ith line has ni elements (1 <= i <= m) in ascending order from left to right, and the elements from the same column are in ascending order from bottom to top. An example of Young table for m = 4, n1 = 6, n2 = 4, n3 = 4, n4 = 1 is the following: 1 2 5 9 10 15 3 6 7 13 4 8 12 14 11 Given n1, n2, ..., nm determine the number of Young tables containing the elements 1, 2, ..., n1+n2+...+nm. Input The input has the stucture: on the first line is: the natural number m (1 <= m <= 20); on the second line are: the numbers n1, n2, ..., nm separated by a space (n1 <= 12). Output The output will contain the number of Young tables that can be built. Sample Input 2 3 2 Sample Output 5 Hint The five Young tables are: 1 3 5 1 2 3 1 2 4 2 4 4 5 3 5 1 3 4 1 2 5 2 5 3 4 */ /* 题意O <SUF>*/ //PKU OJ 1825 import java.math.*; import java.io.*; import java.util.*; public class Main { final static int SIZE = 240; public static void main(String args[]) { Scanner input = new Scanner(System.in); BigInteger ans; int[] s = new int[SIZE]; int[][] young = new int[SIZE][SIZE]; while(input.hasNext()) { int sum = 0; int n = input.nextInt(); for(int i=0;i<SIZE;i++) { for(int j=0;j<SIZE;j++) young[i][j]=-1; } ans = BigInteger.ONE; for(int i=0;i<n;i++) { s[i]=input.nextInt(); sum+=s[i]; young[i][s[i]-1]=0; } //hook-length formula for(int i=2;i<=sum;i++) ans=ans.multiply(new BigInteger(Integer.toString(i))); for(int i=n-1;i>=0;i--) { for(int j=s[i]-1;j>=0;j--) { //A hook length hook(x) of a box x in Young diagram Y(λ) of shape λ //is the number of boxes that are in the same row to the right of it //plus those boxes in the same column below it, young[i][j]=0; if(i!=n-1) young[i][j]+=young[i+1][j]+1; ans=ans.divide(new BigInteger(Integer.toString(young[i][j]+s[i]-j))); } } //ans=n!/MUL(hook(x)) System.out.println(ans.toString()); } } }
