push means to insert new value at the top of the stack.pop means to delete value from the top of the stack.acc. to question stack is empty...now insert 1 and insert 2 now there is a two value in a stack...next operation is pop means delete from the top of the stack...it means 2 is delete ...next operation is insert 3 and 4.now new elements in the stack is 1 3 4. now two times pop...delete two value from stack ....therefore 4 and 3 is delete from the stack now only 1 is left out in the stack...now push 5new elements in the stack is 1 5now next operation is popafter pop only 1 is left out on the top of the stack...
