米哈游笔试大家都做出来几个题啊?本菜鸡又是1道多只写出第一题了#米哈游##春招#1.米小游的色盲视角米小游拿到了一个矩阵,矩阵上每一格有一个颜色,为红色(R)、绿色(G)和蓝色(B)这三种颜色的一种。然而米小游是蓝绿色盲,她无法分辨蓝色和绿色,所以在米小游眼里看来,这个矩阵只有两种颜色,因为蓝色和绿色在她眼里是一种颜色。米小游会把相同颜色的部分看成是一个连通块。请注意,这里的连通块是上下左右四连通的。由于色盲的原因,米小游知道自己看到的连通块数量可能比真实的连通块数量少。你可以帮米小游计算连通块少了多少吗?输入描述:输入描述第一行输入两个正整数n和m,代表矩阵的行数和列数。接下来的n行,每行输入一个长度为m的、仅包含' R '、' G '、’B '三种颜色的字符串。代表米小游拿到的矩阵。1<=n,<=1000。思路:递归,将上下左右相同的颜色块找出来标记为0,代码:import java.util.*;public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); int m = sc.nextInt(); sc.nextLine(); StringBuilder strs = new StringBuilder(""); while (sc.hasNext()){ strs.append(sc.nextLine()); } String str = new String(strs); int[][] number = new int[n][m]; int[][] numberF = new int[n][m]; int nn = 0; for(int i = 0; i < n; i++){ for(int j = 0; j < m; j++){ char temp = str.charAt(nn); if (temp == 'R'){ number[i][j] = 1; numberF[i][j] = 1; }else if (temp == 'G'){ number[i][j] = 2; numberF[i][j] = 2; }else{ number[i][j] = 3; numberF[i][j] = 2; } nn++; } } int truth= 0; for (int i = 0; i < n; i++){ for (int j = 0; j < m; j++){ if (number[i][j] == 0){ continue; }else{ truth++; solve(number, i, j, n, m, number[i][j]); } } } int fake = 0; for (int i = 0; i < n; i++){ for (int j = 0; j < m; j++){ if (numberF[i][j] == 0){ continue; }else{ fake++; solve(numberF, i, j, n, m, numberF[i][j]); } } } System.out.println(truth - fake); }
