1306. Jump Game III

https://leetcode.com/problems/jump-game-iii

Description

Given an array of non-negative integers arr, you are initially positioned at start index of the array. When you are at index i, you can jump to i + arr[i] or i - arr[i], check if you can reach to any index with value 0.

Notice that you can not jump outside of the array at any time.

Example 1:

**Input:** arr = [4,2,3,0,3,1,2], start = 5
**Output:** true
**Explanation:** 
All possible ways to reach at index 3 with value 0 are: 
index 5 -> index 4 -> index 1 -> index 3 
index 5 -> index 6 -> index 4 -> index 1 -> index 3 

Example 2:

**Input:** arr = [4,2,3,0,3,1,2], start = 0
**Output:** true 
**Explanation:**One possible way to reach at index 3 with value 0 is: 
index 0 -> index 4 -> index 1 -> index 3

Example 3:

**Input:** arr = [3,0,2,1,2], start = 2
**Output:** false
**Explanation:** There is no way to reach at index 1 with value 0.

Constraints:

• 1 <= arr.length <= 5 * 104

• 0 <= arr[i] < arr.length

• 0 <= start < arr.length
