//code to choose one of the operations depending on if..else logic Input 3 7-bits variables P,Q,R and a Choice.

//based on the Option do one of the following begin if

if (Choice==1)

//Output value of Q-2

else if (Choice==2)

// Output value of P++

else if (Choice==4)

//Output 1's complement of Q

else if (Choice==6)

//Output value of P-(2*R)

a.     List the combinational circuit elements you will use if you have to build a logic circuit for the above operation.

b.     Design an equivalent combinational circuit which can do the same operation as that of the pseudocode above (Use Logisim).
