Create a RISC V program for each of the following exercises

Create a RISC V program for exercise 3a, 3b and 3c show in the image

Exercise aex3a: Convert -5 to +5 by negating its bits and adding 1. Save your solution as a file named aex3a.asm for possible future use. 4. Exercise aex3b: Calculate the value of 1234-(567+89) without using the sub instruction. Save your solution as a file named aex3b.asm for possible future use. Exercise aex3c: Rotate right by 4 bits the value of Ox0000000000000123. The expected result is Ox3000000000000012, i.e. all hexadecimal digits move right by one position while the rightmost one moves to the front. Save your solution as a file named aex3c.asm for possible future use
