Final Verdict: Rejected
Interview Questions (3)
Find the longest contiguous subarray whose elements sum up to zero.
After finding the longest contiguous subarray whose elements sum up to zero, print the actual subarray. This was a follow-up to the previous problem.
Given the root of a binary tree, return the zigzag level order traversal of its nodes' values. (i.e., from left to right, then right to left for the next level and alternate between).
