Convert java to mips assembley

Comparing each character in the first string with the character at the same index in the second string and compute the number of different characters in the two strings. (ex. Strings_ Difference("atalk","took")=
diff is = 5
and
Compute the difference between the two strings in length.(ex. Strings_Difference("tall","talls") =1 because the string books has one character more than the string book).
The difference between the two strings in length = 1 ----- ( First String is Longer)
