A being the in the front and Z last. I have written a MIPS assembly language code using sw instruction so that I can only replace the 1st character of a string with a character of my choice. Strings can also be entered by the user during the runtime of the program. After that the procedure needs to add the shorter string to the bigger one,calculate its length and print the whole string. , a-z and A-Z. Both methods of using strings in MIPS will be demonstrated below. Just remove 1 from the string length. If the character is not a letter, the program goes to the 'NotLetter' label, and the count of that character is not Data Compression (45 points): Write a MIPS assembly program in the MARS simulator that accepts an input string of size less than 40 characters, and applies the following compression algorithm to the string, and then prints the resulting compressed string. Input : S = “abccdefgaa” and c = ‘a’ Output : 3 Explanation: ‘a’ appears three times in str. Also remember to allocate 1 more byte of storage than you need for the string, to hold that nul byte.
