If you add print(entered_code, correct_code), you will be able to see what the inputs are in the console log. You might get a hint from there.

Find the sum of all multiples of n below m

Sum them up and you'll get 256686.

No way :p

But why should equal 256686?

All multiples of 1 below 717 are: 1, 2, 3, ... ,716. Sum them all up and you'll get that number, not 717.

Darn it, I fixed the issue I had before but now I got this:
Testing for n=1, m=717
Should work for random inputs: 717 should equal 256686

Why?

Thanks a lot! :)

i see, thank you

Here, n = 4 and m = 123.
As for the conditions 'm' is exclusive so 'm' is not included incase it is multiple of 'n'
123 isn't a multiple of 4 so our example will contain [ 4, 8, 12, 16, 20, ...., 120 ] as the final set of
all the multiples of 4 smaller than 123. Now just find the answer by adding all the elements i.e. 1860

It is because incase n>m it will execute the else block on the 7th line of the code.
You can add a extra check when n>m so that it will return "INVALID"

Can someone tell me what are n and m for the first Basic Example where the output should be 1860?
This is the only one that I'm stuck with...

Nice, clear and simple. I like it a LOT!

Lol me neither... I went for importing re
