1933. Check if String Is Decomposable Into Value-Equal Substrings

Leetcode Solutions

One Pass Iteration with Counting

  1. Initialize count to 1 to track the length of the current value-equal substring.
  2. Initialize lengthOf2 to 0 to track the number of substrings with a length of 2.
  3. Iterate through the string s from the second character to the end.
  4. If the current character is the same as the previous one, increment count.
  5. If the current character is different or we reached the end: a. Check if count modulo 3 is 2, increment lengthOf2. b. If count modulo 3 is 1, return false (invalid substring length). c. Reset count to 1 for the next substring.
  6. After the loop, check if lengthOf2 is exactly 1, return true if so, otherwise false.
