Depending on your language, stack may not be supported natively. You may simulate a stack by using a list or deque (double-ended queue), as long as you use only standard operations of a stack. You may assume that all operations are valid (for example, no pop or peek operations will be...

Okay, if you’re threading, you can’t uselistfor a stack and you probably don’t want to usedequefor a stack, so howcanyou build a Python stack for a threaded program? The answer is in thequeuemodule,queue.LifoQueue. Remember how you learned that stacks operate on the Last-In/First...
