CareerCup

I've emailed careercup support 5+ times already (no response) about having this account deleted. Does anyone work actively on this site at all?

I occasionally get emails for recent comments to questions even though I'm not subscribed to this.
The unsubscribe link in this email leads to nothing useful (as I'm not subscribed to this service to begin with).

How do I contact the people who run careercup? How to stop the sporadic spam emails?

I just got this email (which is considered spam now) :


undefined has commented on a question.
You are given an array in which you’ve to find a subarray such that the sum of elements in it is equal to zero.

He algo is nice.
However, In java it is not easy using the hashMap to get the key of values if we use hashmap(index,value). And if we want to use hashtable(value,index), the array cannot have dup as it will have the same key and cover the previous value. We can use a biMap to handle it.
if we don't want to use biMap here is my solution using two hashMap.

static void sumEqZero()
