Inserting an element in a priority queue using linked list requires visiting the list from start to end to determine the proper location to set an element, as maintain the list according to precedence. On the other hand inserting and deleting key element using heap, requires preserving the ...

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...
