/*
    This program executes the concept of a Timer using
    the logic that if a computer's processing speed is 
    2.4GHz, this means that it would take 1s for the 
    computer to complete a for loop from 
    1 to 2.4 * (10 raised to the power 9). So this program
    will execute x number of such for loops to complete x sec
