Please write a complete MIPS assembly language programs for the following questions and print a hardcopy of your code to submit. 1. Swap each pair of elements in the string "chararray" and print the resulting string. There will always be an even number of characters in "chararray". (see loop4.a) 2. "numbers" is an array of five words. Calculate the sum of all elements in "numbers" that are not multiples of 4. Use the and instruction, not div or rem for this question. (See logic1.a file.) 3. "number" is a word. Write it out in base 2 as a sequence of 32 bits. (See logic2.a file.)
