He is doing
currSum = cumSum[j] - curSum[i-1]
Isn’t it going to create problems for i = 0 i.e. the first iteration?
I mean the elemnt at -1 doesn’t exist!
Range problem while calculating current Sum
hello @Prashant-Kumar-1947183015386369
yeah u are right.
handle that case separately using if statement.
ie if i==0 then currSum=cumSum[j].
