Data Structures for Coding Interviews in JavaScript

Challenge: A Subarray with a Sum of 0

Explore methods to identify a consecutive sublist within an array whose sum equals zero. Understand how hashing and hash tables can be applied to efficiently determine the presence of such subarrays, enhancing your problem-solving skills for coding interviews.

We'll cover the following...

Statement

Given a list containing both positive and negative integers, determine if there exists a sublist of consecutive elements whose elements sum to zero. Return TRUE if such a sublist exists; otherwise, return FALSE.

Constraints:

  • 1≤1 \leq arr.length
