This problem is from https://acm.hdu.edu.cn/ I don't have the exact link to the problem though. ![ ](codeforces)

I tried many approaches , either they are in efficient or way too complicated .

How come? Could you add a bigger screenshot, so it would be clear where its from — to be sure it's not ongoing contest?

My approach is also linear, but I am not sure how to explain it.my approach was to work on individual element as subarray sum need to be > 0 , to be X as majority element, so assign X as +1 and rest element will contribute -1.so we could make consecutive blocks of 0 and >0 and apply running sum , before this we have to push all identical element in vector array storing their index.
But I guess this is your question
