Sep 30, 2010 · Every time you encounter an operator (+,-,/,*) pop twice from the stack and place the operator between them. Push that on the stack: So if we have 53+2* we can convert that to infix in the following steps: Push 5. Push 3. Encountered +: pop 3, pop 5, push 5+3 on stack (be consistent with ordering of 5 and 3) Push 2.

Mar 6, 2017 · I believe the spring loaded stack of plates is correct, as the source for the term PUSH and POP. In particular, the East Campus Commons Cafeteria at MIT had spring loaded stacks of plates in the 1957-1967 time frame. The terms PUSH and POP would have been in use by the Tech Model Railroad Club. I think this is the origin.

May 11, 2010 · Push/Pop operations are actually commonly applied to a "stack" not always exactly the same thing as a "linked list", and while linked lists can provide you the basis for a queue or a stack, with equal ease, semantically the FIFO/LIFO criteria thing is how you decide what the original guy is asking.

Jan 1, 2018 · When the stack size is 0, there is nothing on the stack, because there are no list indices less than 0. After the first push, the stack size is 1, so there is exactly one list element that corresponds to a stack element: stack[0]. If you then pop an element, the stack size is again reduced from 1 to 0, so the stack is again empty.

Sep 12, 2013 · In the current code, at the first push, your code with stack[*top++] = item, with the post increment attempts to assign the value to the current value of *top which is -1 and then increment, which is wrong. With respect to this modification of …

Dec 5, 2013 · << endl; cin >> z; push(z); pop(); print(); return 0; } We thought about creating a new StackElement, that would work as a 'pseudo'-StackElement and would always stay on top so that the 'real' element on the top would always be the predecessor of the pseudo-Element - but we think this would be against how the stack should work.

Jan 23, 2013 · For example, in the best case scenario push and pull operations will be O(1) because the number of steps it takes to remove from or add to the stack are going to be fixed. Regardless of the value, the process will be the same. I'm trying to envision how a sequence of events such as push and pop can degrade performance from O(1) to O(n^2).

I notice that after writing the address of the argument to the stack, you then revert the stack pointer before calling printf. So in both examples, the stack pointer is pointing to the original first argument when calling printf , which might explain why it prints the first argument in both cases.

Jan 3, 2011 · A standard term for inserting into stack is PUSH and for remove from stack is POP. Stack is managed via stack intended CPU register, also called stack pointer, so when CPU perform POP or PUSH the stack pointer will load/store a register or constant into stack memory and the stack pointer will be automatic decreased xor increased according ...
