ZDou201902222047819：做完之后对我的认识就是数据结构忘了、操作系统忘了、Java忘了

Pluto_Love：import java.util.Scanner; public class DoMain { public static void main(String[] args) { Scanner in = new Scanner(System.in); int T = in.nextInt(); int[][] array = new int[T][4]; for (int i = 0; i < T; i++) { array[i][0] = in.nextInt(); array[i][1] = in.nextInt(); array[i][2] = in.nextInt(); array[i][3] = in.nextInt(); } foo(array); } public static void foo(int[][] arr) { System.out.println(arr.length); for (int i = 0; i < arr.length; i++) { while (true) { if (arr[i][0] == 0) { System.out.println("Yes"); break; } else if (arr[i][0] == -1) { System.out.println("No"); break; } arr[i] = cal(arr[i]); } } } public static int[] cal(int[] ar) { if (ar[3] >= 2) { ar[3] -= 2; ar[0] -= 1; } else if (ar[3] == 1 && ar[2] >= 1 && ar[1] >= 1) { ar[3] -= 1; ar[2] -= 1; ar[1] -= 1; ar[0] -= 1; } else if (ar[3] == 1 && ar[2] == 0 && ar[1] >= 3) { ar[3] -= 1; ar[1] -= 3; ar[0] -= 1; } else if (ar[3] == 0 && ar[2] >= 3) { ar[2] -= 3; ar[0] -= 1; } else if (ar[3] == 0 && ar[2] == 2 && ar[1] >= 2) { ar[2] -= 2; ar[1] -= 2; ar[0] -= 1; } else if (ar[3] == 0 && ar[2] == 1 && ar[1] >= 4) { ar[2] -= 1; ar[1] -= 4; ar[0] -= 1; } else if (ar[3] == 0 && ar[2] == 0 && ar[1] >= 6) { ar[1] -= 6; ar[0] -= 1; } else { ar[0] = -1; } return ar; } }这次格式在不对就没法了
