问题描述:

代码示例:

//蛇形矩阵
#include <bits/stdc++.h>
using namespace std;int main(){int n;cout << "输入样例" << endl; cin >> n;int k = 1; for(int i = 0; i < n; i++){if( i %2 == 0){//单数行for(int j = 0; j < n; j++){	cout << k++ << " ";}} else{//双数行,逆置for(int j = k+n-1; j >= k; j--){	cout << j << " ";}k += n;//保证k在下一行的初始值不出错}cout << endl;}return 0;
} 

运行结果:
