Create a RISC V Program for each of the following exercises

Exercise aex3a: Convert -5to +5by negating its bits and adding 1.Save your solution as a file named aex3a.asm for possible future use.

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 0x0000000000000123.The expected result is 0x3000000000000012,i.e. all hexadecimal digits move right by one position while the rightmost one moves to the front. Save your solution as a filenamedaex3c.asm for possible future use.
