Thank you! Sure I usually make upto 3 only.

[@utsavpathak2122]

I really liked the way you explained the problem but it is still tough to come up with the mathematical approach. Great video. Can I get the dp solution too ? I was also thinking about a dp approach to the problem but i couldnt come up with that. Thankyou

[@preetu391]

Thank you!
Here's the dp solution with memoization - github.com/preetu391/LeetCode-Contest-Solutions/blob/main/Weekly%20Contest%20390/Apply%20Operations%20to%20Make%20Sum%20of%20Array%20Greater%20Than%20or%20Equal%20to%20k.cpp
You can always check description box for codes. I usually put up different approaches with working code on my github.
