Did you try to take input by scanf and printf?

Try using fast i/o :-

ios::sync_with_stdio(false); cin.tie(nullptr); cout.tie(nullptr);

On every solve or pro function call you allocate lots of vectors and than copy them to another function calls, allocating new vectors again and again.

You should probably create vectors once in main function and then pass it into functions by references, like that void solve(vector<vector<int>>& mat, int p, vector<vector<int>>& result). Or even make them global
