Explanation:

Steps

  1. Define a palindrome check function:
    • A number is a palindrome if it reads the same forwards and backwards.
    • Reverse the number and compare it with the original.
  2. Iterate through numbers:
    • Start from 1 and check each number to see if it is a palindrome.
    • Use a counter to keep track of how many palindrome numbers have been printed.
    • Stop when n palindromes have been found.
  3. Output: Print the palindrome numbers.
