The following sequence of the operations
is performed on a stack PUSH(10), PUSH(20), POP, PUSH(10), PUSH(20), POP, POP,
POP, PUSH(20), POP the sequence of values popped out is 20,20,10,10,20.
Stack is collection of elements, that
follows the LIFO order. LIFO
stands for last In first out, which means element which is inserted most
recently will be removed first.
A stack has a restriction that insertion
and deletion of element can only be done from only one end of stack and we call
that position as top. The
element at top position is called top
element. Insertion of element is called push and deletion is called
pop.
