Please don$$t give me false answer again...I really need this to be right,I really need to learn the correct information, so please don$$t answer this if you are not sure about the answer, thanks a lot! Please teach me$$Problem $2(15\backslash \%)$ Recall that stacks have two operations, push and pop, which add and remove keys from the top of the stack. Prof. Chen wants to extend the definition of a stack by adding two new operations called insert and eject. Insert $\backslash (($k$)\backslash )$ adds a new key $\backslash ($ k $\backslash )$ to the bottom of the stack, and Eject$()$ reads and removes the key at the bottom of the stack. Use two normal stacks $($with only push and pop operations$)$ to implement one stack that supports push, pop, insert, and eject operations. Briefly explain why your implementation is correct and analyze the worst$-$case running time $($in $\backslash (\backslash$Theta $\backslash )-$notation$).$ You do not have to be efficient. $\backslash (\backslash$Theta$($n$)\backslash )$ time for each operation suffices.
