Hey guys,

Exp: ~6 YOE

I was asked 2 LP's - Deep Dive, Ownership
I answered well.

Easy/Medium level questions.

1. Range query based problem - return subarray that sums to 0
   I gave working code
2. Prority Queue based problem - given 2 sorted lists and integer k, return first k pairs with least/mininum sums, in increasing order.
   I gave closely working code but missed a corner case.

Verdict: Positive
