Leetcode Solutions

Generating Palindromes by Half-Length Manipulation

  1. Calculate the base number for the first half of the palindrome.
  2. Iterate over each query in queries.
  3. For each query, calculate the first half of the palindrome by adding the query number minus one to the base number.
  4. Check if the first half exceeds the maximum possible value. If it does, append -1 to the result list.
  5. If the first half is within the valid range, construct the full palindrome.
  6. For even intLength, mirror the entire first half.
  7. For odd intLength, mirror all but the middle digit of the first half.
  8. Append the constructed palindrome to the result list.
  9. Return the result list.
