Here$$s a sample Computer Science program question:

$---$

$**$Question:$**$

Write a Python program to determine if a given string is a palindrome. A palindrome is a word, phrase, or sequence that reads the same backward as forward $($e$.$g$.,$ "madam" or "racecar"$).$ Ignore spaces, punctuation, and case sensitivity$.$

$**$Requirements:$**$

$1.$ Prompt the user to enter a string.

$2.$ Remove all non$-$alphanumeric characters from the string and convert it to lowercase.

$3.$ Check if the cleaned string reads the same forwards and backwards.

$4.$ Print $`"$The string is a palindrome"$`$ if the string meets the condition, and $`"$The string is not a palindrome"$`$ otherwise.

$**$Sample Input$/$Output:$**$

$-**$Input$**$: "A man, a plan, a canal, Panama!"

$**$Output$**$: "The string is a palindrome."

$-**$Input$**$: "Hello, World!"

$**$Output$**$: "The string is not a palindrome."

$**$Correct Answer Explanation:$**$

A palindrome remains the same when read from both ends. By removing non$-$alphanumeric characters and lowering the case, we normalize the string for easy comparison.
