男人就是要写代码！

#include <iostream>
using namespace std;

    int n,m,x = 0,y = 0,d,num;
    cin >> m >> n;
    int dx[4] = {0,1,0,-1},dy[4] = {1,0,-1,0};

    for(x = 1,y = 1,d = 0,num = 1;num <= n*m;num++)
    {
        if(a[x][y] == 0)
            a[x][y] = num;
        if(x+dx[d] < 1 || y+dy[d] < 1 ||x+dx[d] > m || y+dy[d] > n||a[x+dx[d]][y+dy[d]] != 0)//越共探头查一下下一次有没有出界
        {
            d++;
            if(d > 3)
                d = d%3 - 1;
        }

    }
