what is the final stack after the following operations on an empty stack
push(4),pop(),p ush(7),push(8), pop(),push(7),p ush(9),pop(),pu sh(8),push(5)

why are you asking this question?

       bottom{XXXX}top of the stack   XXXX be the elements of the stack 

emty          { }
push(4)      { 4 }
pop()          { }
push(7)       { 7 }
push(8)       { 7 8 }
pop()           { 7 }
push(7)       { 7 7 }
push(9)       { 7 7 9 } 
pop()          { 7 7 } 
push(8)       { 7 7 8 }
push(5)       { 7 7 8 5 }

that's it
