TODO 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 <= 10^{5}
  • s[i] is either '0' or '1'.
  • s[0] == '0'
  • 1 <= minJump <= maxJump < s.length

TODO Approach

Write your approach here.

TODO Python

class Solution:
    def canReach(self, s: str, minJump: int, maxJump: int) -> bool:

TODO C++

class Solution {
public:
    bool canReach(string s, int minJump, int maxJump) {
        
    }
};
