#include <bits/stdc++.h>
using namespace std;
const char el = '\n';
typedef long long ll;
bool flp;
void submit(int x, int y) {
if (flp)
cout << y << ' ' << x << el;

if (n == 1 && m == 1) {

}
if (n == m) {

for (int i = 1; i < n; i++) submit(1, i);

}
for (int i = 1; i <= m; i++) submit(1, i);
for (int i = 1; i <= m; i++) submit(n, i);
int k = (m + 1) / 2;
if (m & 1) {
for (int i = k + 1; i <= n - k; i++) submit(i, k);
return 0;
}
for (int i = k + 2; i < n - k; i += 2) submit(i, k), submit(i, k + 1);
return 0;
}
这程序好像有点Bug,我给组数据试试?
