Push(S, x). Pushes a value x into a stack S

Solution

In Push(S,x)

Here Stack address is saved in stack pointer(SP) and after Pushing value x onto stack SP may get incremented or decremented depending whether stack growing upwards or downwards.

1) If SP after Push is incremented then stack is growing upwards

2) If SP after Push is decremented then stack is growing downwards.

SP is 4 bytes long (32-bit address) or 8 bytes long(64-bit address)

Hence above statement is TRUE
