2414. Length of the Longest Alphabetical Continuous Substring

Leetcode Solutions

Iterative Approach with Two Pointers

  1. Initialize max_length to 0 to store the maximum length of the continuous substring found so far.
  2. Initialize start to 0 to mark the beginning of the current continuous substring.
  3. Iterate through the string s starting from the second character (index 1).
  4. For each character at index i, check if it is consecutive to the character at index i-1.
  5. If it is consecutive, continue to the next iteration.
  6. If it is not consecutive, calculate the length of the current continuous substring as i - start and update max_length if it is greater than the current max_length.
  7. Reset start to the current index i.
  8. After the loop, update max_length with the length of the final substring by comparing it with len(s) - start.
  9. Return max_length as the result.
