Hello,

I need help understanding the operation limits for old USACO Silver. How many operations can be done maximum before timeouts occur for test cases in old USACO Silver problems?

Depends on the operation, you can find some discussion here: How many operations per second can my solution be? - Codeforces.

To test on USACO you can do something like the following:

Problem: USACO

Code:

```
#include <iostream>
uint32_t solve(uint32_t N) {
uint32_t ans = 0;
while (N) ans ^= N--;
return ans;
}
int main() {
int N; std::cin >> N;
if (N == 6) std::cout << 115; // answer to first test case
else if (solve(1000000000+N)) std::cout << 43964210127; // answer to second test case
}
```

Result:

As you can see, 10^9 xors take less than a second. Same for unsigned addition.
