    2609 - Find the Longest Balanced Substring of a Binary String.

    Easy

    You are given a binary string s consisting only of zeroes and ones.

    A substring of s is considered balanced if all zeroes are before ones and the number of zeroes is equal to the number of ones inside the substring. Notice that the empty substring is considered a balanced substring.

    Return the length of the longest balanced substring of s.

    A substring is a contiguous sequence of characters within a string.

    Example 1:

    Input: s = "01000111"

    Output: 6

    Explanation: The longest balanced substring is "000111", which has length 6.

    Example 2:

    Input: s = "00111"

    Output: 4

    Explanation: The longest balanced substring is "0011", which has length 4.

    Example 3:

    Input: s = "111"

    Output: 0

    Explanation: There is no balanced substring except the empty substring, so the answer is 0.

    Constraints:

    • 1 <= s.length <= 50

    • '0' <= s[i] <= '1'
