思路及代码

#include<iostream>
using namespace std;
int main(){
//input 多组
//input M,N int 1<= <=20
//input M 行 N 列 数据
//initialize list
    int M, N;
    while (cin >> M >> N){
        int list[M][N];
        for (int i = 0; i <= M-1; i++){
            for (int j = 0; j <= N-1; j++){
                cin >> list[i][j];
            }
        }
//solution
//遍历 i j output i+1,j+1
        for (int i = 0; i <= M-1; i++){
            for (int j = 0; j <= N-1; j++){
                if (list[i][j] != 0){
                    cout << i+1 << ' ' << j+1 << ' ' << list[i][j] << endl;
                }
            }
        }
        cout << endl;
    }
    return 0;
}
