yeah that would be helpful

Can you please explain me this section of code actually i am quite dull in recursion
how did you updated count of nodes from child nodes.

root->cnt = root->cnt - cnt;
if(root->cnt > 1)
{
	lli n = (root->cnt / 2);
	lli tmp = (height / 2) * (height / 2);
	ans += n * tmp;
	cnt += 2 * n;
}

delete root;
return cnt;

For this there would be a recursive call to dfs( ) function again.
if you are not good at recursion , try studying it from basics , like finding N! using recursion and Fibonacci number.

Bro can you also make content on network flow algorithms?

77

concepts like Centroid decomposition and flow graph i will be covering in part 2 , so yes i will be making lectures on those

Any plan to make more videos on combinatorics?
Btw your graph series was very helpful.

@waqar_ahmad224 will you be adding more videos on number theory I really like your videos.
