Solve problems that are commonly asked in C++ coding interviews related to common data structures.

Ace the C++ Coding Interview

Data structures are among the fundamentals of computer science and are often a core decision in developing efficient programs. They are categorized as a vital benchmark of computer science knowledge when it comes to industry interviews. This module contains a detailed review of common data structures in C++. We'll also become well-equipped with different data structures by implementing them.
By the end of this module, we'll have expertise in solving problems in data structures.

Data Structures

# 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:**

- $1 \leq$ `arr.length` $\leq 10^{3}$
- $10^{-3} \leq$ `arr[i]` $\leq 10^{3}$
