Final Value of Variable After Performing Operations.py

#!/usr/bin/python

'''
There is a programming language with only four operations and one variable X:
++X and X++ increments the value of the variable X by 1.
--X and X-- decrements the value of the variable X by 1.
Initially, the value of X is 0.
Given an array of strings operations containing a list of operations, return the final value of X after performing all the operations.
