hi @suryansh771 a simple nested loop has been used, is there anything particular you did not understand?

#3

what is meant by cummulative sum and whats the flow of the code ,pls privide the flowchart

#4

@suryansh771 cumulative sum means that we add the all the elements that have occured until now
like for array
1 2 3 4 5
cumulative sum will be:
1 3 6 10 15

at each step, csum[i] = csum[i-1] + arr[i]

The flow of control can be understood from the program also, try to do a dry run once using pen and paper. Did you understand maximum subarray 1? Its just a small extension of that.
