Hey @sheikhhaji18

On;y 5% testases are running
so that means your logic is Incorrect and not considering many cases
[1,2,3,4,5] is one of them

My suggestion is u should refer to Solution Editorial of the problem :https://leetcode.com/problems/best-time-to-buy-and-sell-stock-iii/discuss/937778/C%2B%2B-oror-Full-Explained-Code-oror-Video-oror-O(N) :slight_smile:

2) when there is no zero in the array i will just use the approach ofbest time buy and sell two approach

You are not able to keep track of max tranactions ==2
See for this [1,5,2,1,5,2,1,5]
Ur output =12
expected =8

U are nowhere considering the fact that maximum transaction u can do is 2

#7
