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:

\n\n\n\n

Return true if you can reach index s.length - 1 in s, or false otherwise.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "011010", minJump = 2, maxJump = 3\nOutput: true\nExplanation:\nIn the first step, move from index 0 to index 3. \nIn the second step, move from index 3 to index 5.\n
\n\n

Example 2:

\n\n
\nInput: s = "01101110", minJump = 2, maxJump = 3\nOutput: false\n
