Data Structures for Coding Interviews in Java

Challenge: A Subarray with a Sum of 0

Explore methods to identify if a list contains a consecutive subarray whose sum equals zero. Learn to implement this solution effectively in Java using hash tables, understand algorithm constraints, and prepare for common coding interview questions with practical coding exercises.

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
