Hey @pragyanvarshney
Your approach is unfortunately incorrect. Please have a look at this https://www.geeksforgeeks.org/maximum-profit-by-buying-and-selling-a-share-at-most-k-times/

My approach is simply to generate all transactions possible then select the largest k transactions. Where am I wrong?

@pragyanvarshney
A transaction can start only after a previous transaction ends. They cant overlap. It is a DP question. You’re solving it using a greedy approach.

I hope I’ve cleared your doubt. I ask you to please rate your experience here
