DONT USE JAVA! ITS A SPARC ASSEMBLY LANGUAGE! It has to be in a .m file. use
terminal
Notes:
1.  Make sure to declare word elements before declaring bytes or strings.
2.  After using the scanf function, you can then use either the ld or ldub commands to access
the input values. The command ld is for the word size elements and ldub is for the byte size
elements.
Write a program that accepts a string from the user. You can assume the length of the string will
be less than 30 characters and only alphabetical letters are entered. Your program should then
prompt the user to enter a letter (either lower case or upper case) After this, you should 1)
display the string with only lower case letters, 2) display the length of the string, 3) count the
number of occurrences of the letter entered (upper or lower case), 4) store the string with the
letter removed (upper and lower case occurrences) and display the shortened string, and 5) ask
the user if they want to continue or not. Error checking on user input is required for the single
letter input and the option to continue or not. Here is an example: Please enter in a string of a
maximum of 30 letters: iloVeAssEmBlyLanguAge Please enter a letter: e lestring of a maximum
of 30 letters laysAssEmail angles The string in lower case is: iloveassemblylanguage The length
of the string is 21 characters The letter e appears 3 times The revised string is:
ilovassmblvlanguag Would you like to enter in another string n)? D
