1871\. Jump Game VII

Medium

You are given a **0-indexed** binary string `s` and two integers `minJump` and `maxJump`. In the beginning, you are standing at index `0`, which is equal to `'0'`. You can move from index `i` to index `j` if the following conditions are fulfilled:

*   `i + minJump <= j <= min(i + maxJump, s.length - 1)`, and
*   `s[j] == '0'`.

Return `true` _if you can reach index_ `s.length - 1` _in_ `s`_, or_ `false` _otherwise._

**Example 1:**

**Input:** s = "011010", minJump = 2, maxJump = 3

**Output:** true

**Explanation:**

In the first step, move from index 0 to index 3.

In the second step, move from index 3 to index 5. 

**Example 2:**

**Input:** s = "01101110", minJump = 2, maxJump = 3

**Output:** false 

**Constraints:**

*   2 <= s.length <= 105
*   `s[i]` is either `'0'` or `'1'`.
*   `s[0] == '0'`
*   `1 <= minJump <= maxJump < s.length`
