Written in assembly using MARS-ARM. Can you please help me write this in assembly?

This ARM program will ask the user to enter a string of characters and then report whether the string is a palindrome.

pal.in.drome, n. a word, line, verse, etc., reading the same backward as forward, as

Madam, Im Adam Poor Dan is in a droop Doc, note. I dissent. A fast never prevents a fatness. I diet on cod.

Eg.

Please enter a character string or press Enter to exit: madam im adam

The string madam im adam is a palindrome.

Please enter a character string or press Enter to exit:

Program terminated.

Ignore all blank space within the string when determining whether the string is a palindrome. Palindromes may contain any alphanumeric characters.

Must be able to handle spaces and punctuation (including apostrophes) and must be case insensitive.

Thanks!
