Understanding the Jump Game I V Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given an array of integers arr, you are initially positioned at the first index of the array. In one step you can jump from index i to index: i + 1 where: i + 1 < arr.length. i - 1 where: i - 1 >= 0. j where: arr[i] == arr[j] and i != j. Return the minimum number of steps to reach the last index of the array. Notice that you can not jump outside of the array at any time.

Examples
arr = [100,-23,-23,404,100,23,23,23,3,404]3You need three jumps from index 0 --> 4 --> 3 --> 9. Note that index 9 is the last index of the array.
arr = [7]0Start index is the last index. You do not need to jump.
arr = [7,6,9,6,9,6,9,7]1You can jump directly from index 0 to index 7 which is last index of the array.
Constraints
