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:
