The following store instructions are executed.

$stp29,30,[sp,-64]!$

$stp21,22,[sp,16]$

$stp19,20,[sp,32]$

The state of the registers before the stores are executed is as follows:

Show the contents of the stack immediately after the third store instruction has completed

execution. Clearly indicate where the stack pointer is$.$ If the contents of a stack location are

unknown, put a $\text{'}?\text{'}$ in that location.

The stack pointer $($sp$)$ contains the value

after the last store instruction

completes.
