It is the first project euler problem which I encountered at codewars. In this Kata we have to find the sum of all the multiples of 3 or 5 below a given number. We loop from 1 to a number just 1 less than the given number and keep adding the numbers which are factor of either 3 or 5 to a sum variable which we had initialized to 0.

In the end we return the value of sum as the answer to this kata.

Please go through the code for a better understanding.
