# Solution: Problem Challenge 3: Cycle in a Circular Array

## Problem Statement

We are given an array containing positive and negative numbers. Suppose the array contains a number ‘M’ at a particular index. Now, if ‘M’ is positive we will move forward ‘M’ indices and if ‘M’ is negative move backwards ‘M’ indices. You should assume that the **array is circular** which means two things:

- If, while moving forward, we reach the end of the array, we will jump to the first element to continue the movement.
- If, while moving backward, we reach the beginning of the array, we will jump to the last element to continue the movement.
