Leetcode Solutions

Approach: Stack

  1. Initialize an empty stack.
  2. Iterate through each character in the string.
  3. For each character, check if it matches the character at the top of the stack.
  4. If it matches, increment the count at the top of the stack.
  5. If the count equals k, pop the stack k times to remove the characters.
  6. If it does not match, push the character onto the stack with a count of 1.
  7. After iterating through the string, reconstruct the string from the stack by appending characters to the result string based on their counts.
  8. Return the reconstructed string.
