Data Structures for Coding Interviews in C++

Solution: A Subarray with a Sum of 0

Explore how to detect a subarray with a sum of zero in an array of integers using a hash table in C++. Learn to track cumulative sums efficiently and grasp the algorithm's time and space complexity 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 ≤103\leq 10^{3}
