QUESTION $1$: You have multiple nested subroutine like a subroutine ofsorting and there is another subroutine which is being used in that subroutine asnested like swap in sorting so if we are in swap make program in such a waythat it will return from swap to directly in main program not in sorting. If thereare more than many nested subroutines like in Armstrong there is subroutine ofArmstrong in which there is subroutine to find power of number in power ofnumber subroutine we are calling subroutine of multiply then the ret of multiplymust be directly take you to main program out of all the subroutines directly.NOTE: After returning from last nested subroutine the state of stack must besame as it was before calling the first subroutine.
