2609. Find the Longest Balanced Substring of a Binary String

Leetcode Solutions

Counting's and's

  1. Initialize two counters for 0's (zeroCount) and 1's (oneCount) and a variable for the maximum length (maxLength).
  2. Iterate through each character in the string.
    • If the character is a '0', increment zeroCount.
    • If the character is a '1', increment oneCount.
  3. After each increment, check if zeroCount is equal to oneCount and update maxLength if necessary.
  4. If a '1' is followed by a '0', reset both zeroCount and oneCount.
  5. Return maxLength * 2 as the final result, since each balanced substring contains an equal number of 0's and 1's.
