Mostly implemented in golang. Sharing the beautiful code :)

I recommend to not look at the solutions and try to solve on your own. It's fun!

These gists will be removed by the end of 2023.

1.py

""" Problem Statement : If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000. """

sum = 0

for i in range(1,1000) :
    if(i%3 == 0 or i%5 == 0) :
        sum += i

print("The sum of all the multiples of 3 or 5 below 1000 is : "+ str(sum))
