What are positive and negative indices?
Positive indices are applied when the search begins from left to right. In negative indices, the search begins from right to left. For example, in the array list of size n the positive index, the first index is 0, then comes 1, and until the last index is n-1. However, in the negative index, the first index is -n, then -(n-1) until the last index -1.
