Write a method in basic MIPS assembly (no pseudo instructions) which determines whether or not an input string is a palindrome.
.data
String0:
.asciiz ""
String1:
.asciiz "a"
String2:
.asciiz "b"
String3:
.asciiz "aba"
String4:
.asciiz "abba"
String5:
.asciiz "baab"
String6:
.asciiz "ababa"
String7:
.asciiz "aabba"
String8:
.asciiz "abbab"
Is:
.asciiz" is a palindrome. "
IsNot:
.asciiz" is not a palindrome. "
