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 listint 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+1for (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;
}
