为什么这就A了？有什么不同吗？
```cpp
#include <bits/stdc++.h>
#define in(a) scanf ("%d", &a)
#define mem(a, b, l) for(int i = 0; i < l; i ++) a[i] = b;
#define out(a) printf ("%d", a)
using namespace std;
int n, t;
char s[51];
int main()
{
in (n), in (t);
scanf ("%s", s);
while (t--)
for (int i = 0; i < n-1; i ++)
if (s[i] == 'B' && s[i+1] == 'G')
swap (s[i], s[i+1]), i ++;
printf ("%s", s);
return 0;
}
```
