* 1345. Jump Game IV
|
|
* 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.
