What are the different operations that can be performed on a stack?

Machine organization The following operations are performed on a stack: PUSH A, PUSH B, POP, PUSH C, POP,POP,PUSH D, PUSH E, POP, PUSH F. What does the stack contain after each operation?

Knowledge of Stack Data Structure is a must. Create a stack data structure that can hold at most 10 items. Operations: Push, adds a new item on top of the stack. Pop, removes the item on top of the stack Top, returns the top item on top of the stack To add item on top of the stack, enter PUSH followed by the value ex. PUSH 20 To remove the item on top of the stack, enter POP ex. POP To print the value on top of the stack, enter TOP and it will print the top value and exit the loop. ex. TOP Rest assured that the input will not generate IndexOutOfBoundsException Input 1. Operation e.g. PUSH 10, POP, TOP Description PUSH operation always comes first. Number of POP operations is equal to number of PUSH operations TOP will be the last. Sample PUSH·10 PUSH·20 POP TOP Output Enter·PUSH·N·to·add·value,·N·is·int·value Enter·POP·to·remove·value Enter·TOP·to·print·final·result: PUSH·10 PUSH·20 POP TOP 10
