201909-3 字符画 java 运行错误

Question

看了一些大佬的代码思路，自己敲了一遍，测试的时候结果貌似都对了（？？？）可是一提交到系统就报错。本人愚笨，请各位帮忙看看。

import java.util.Scanner;

public class Main {

    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);
        String[] input = scanner.nextLine().split(" ");
        int m = Integer.parseInt(input[0]);
        int n = Integer.parseInt(input[1]);
        String[] data = scanner.nextLine().split(" ");
        int p = Integer.parseInt(data[0]);
        int q = Integer.parseInt(data[1]);
        int s = p*q;

        int[][][] color = new int[n][m][3];

        for(int i=0 ; i<n ; i++) {
            for(int j=0 ; j<m ; j++) {
                String line = scanner.nextLine();
