Python code to check if a number is a palindrome using iteration: def is_palindrome(num): str_num = str(num) start = 0 end = len(str_num) - 1 while start < end: if str_num[start] != str_num[end]: return False start += 1 end -= 1 return True print(is_palindrome(121)) ...
In this example, the program correctly recognizesradaras a palindrome andpythonas not a palindrome using thedequemethod, highlighting the efficiency and simplicity of utilizing a double-ended queue for palindrome checks in Python.
