2081. Sum of k-Mirror Numbers

Leetcode Solutions

Enumerate Palindromes in Base- and Base-k

  1. Initialize a sum to 0 and a count of found k-mirror numbers to 0.
  2. Loop through numbers starting from 1 to generate base-10 palindromes.
    • For each number, generate two palindromes: one with an odd number of digits and one with an even number of digits.
    • Convert each palindrome to base-k and check if it is a palindrome in that base.
    • If it is a k-mirror number, add it to the sum and increment the count.
  3. Continue the loop until the count of k-mirror numbers reaches n.
  4. Return the sum.
