A computer with a register ile, but without PUSH and POP instructions, is to be used to implement a stack. The computer does have the following register indirect addressing modes:

Show how these instructions can be used to provide the equivalent of PUSH and POP by using the instructions and register R6 as the stack pointer.

Register indirect + increment: LD Rj Ri ST Rj Ri Decrement + register indirect: LD Rj Ri ST Rj Ri Rj+M[Ri] RiRi+1 M[Ri] - Rj RiRi+1 RiRi -1 Rj - M[Ri] Ri Ri-1 M[Ri] - Rj
