Python Queue and Stack.

Using lists to modeling behavior of these Data Structures.

Queue

A Queue is a linear Data Structure using the principle of FIFO to handle data.

FIFO stands for First In First Out.

Time Complexity: O(1)

Stack

A Stack is a linear Data Structure using the principle of LIFO or FILO to handle data.

LIFO stands for Last In First Out.

FILO stands for First In Last Out.

Time complexity: O(1)

queue.py - Python script for the Queue.

stack.py - Python script for the stack.

simulation.py - Python script in which I use two stacks to simulate a queue.
