The interview process involved two coding questions.

The first question was to validate a string of parentheses using a stack.

The second question, Jump Game, required determining if you could reach the end of an array by making jumps.

The first question asked was the Jump Game.

In this problem, you are given an array of non-negative integers. You start at the first index, and each element in the array represents the maximum length you can jump from that position. The goal is to determine if you can reach the last index of the array.
