How to test for multiple inputs

[MdNihal05]

How to stress test if there are multiple inputs like a graph of n nodes a array permutation of n nodes and Binary string of length n Or some strings etc ...

This seems like very specific to a problem. Can you share a sample problem on which you want to stress test?

You can do it like:

const int MAX_N = 100;
int n = rand(1, MAX_N);
int q = rand(1, 10);

vector<pair<int, int>> tree = gen_tree(n);

and so on. You can generate a perumatation by taking an array of size n, and shuffling it randomly.
