1974. Minimum Time to Type Word Using Special Typewriter

Leetcode Solutions

Optimal Pointer Movement

  1. Initialize the total time time to 0 and set the current position current_pos to 'a' (which is 0 when considering 'a' as 0, 'b' as 1, ..., 'z' as 25).
  2. Iterate over each character in the word.
  3. For each character, calculate its position target_pos in the same way as current_pos.
  4. Calculate the clockwise distance clockwise_dist and the counterclockwise distance counterclockwise_dist between current_pos and target_pos.
  5. The movement time for the current character is the minimum of clockwise_dist and counterclockwise_dist.
  6. Add the movement time and 1 (for typing the character) to time.
  7. Update current_pos to target_pos.
  8. After the loop, return the total time time.
