$1.$ Write a C program that decodes an input machine code. Your program should be able to decode the R$,$ I, S$,$ SB$,$ and UJ type instructions listed below. We will only test the following instructions.

$$add addi

and andi

beq bge

blt bne

jal jalr

lb lh

lw

or ori

sb sh

sll slli

slt slti

sltiu sltu

sra srai

srl srli

sub sw

xor xori

When the program is started, your program will print $$Enter an instruction:$$ and receive one $32-$bit machine code from user. Then, the program will decode the machine code and print the information $($type and values of individual fields of the instruction format$)$ of the instruction. The following is the example execution of the program. The program must produce the following sample results in the exact same format.

Example$1$ :

Enter an instruction:

$00000000001100100000001010110011$

Instruction Type: R

Operation: add

Rs$1$: x$4$

Rs$2$: x$3$

Rd: x$5$

Funct$3$: $0$

Funct$7$: $0$

Example $2$:

Enter an instruction:

$00000000101001100111011010010011$

Instruction Type : I

Operation: andi

Rs$1$: x$12$

Rd: x$13$

Immediate: $10($or $0$xA$)$
