Now keep in mind that when you are deleting a node i, it might not be a single node, but a collection of nodes. Also par[i] can be a collection of nodes. You can only delete i when par[i] is deleted. More would be the time taken to delete par[i], more would the node i ...
Brutal-force solution is not hard to think about. But linear space input usually indicates O(n) DP solution. State design: dp[i]: total sum until index i; and then you need some number manipulation to figure out the equation. https://www.hackerrank.com/challenges/sam-and-substrings/edito...
I'd like to thankkevinsogofor testing the problems and his contribution towards fixing problem statements and editorials. It's always a pleasant experience to work with him. I have tried to create a balanced and interesting problem set. I suggest you read all problems, since there are subtask...
