Project Euler

Just sign in and see. I don't think you need that much at first.

If you are don't like math, that might be a good way to prepare for your future classes...

I think Project Euler looks fun, but does it really help with interviews? I have never heard of anything like that. It probably doesn't.

you can just wikipedia most of everything

first problem:
is (number) modulus 3 OR 5 == 1?
then add it to sum

loop that 1000 times

>>8600378
oops
=== 0 (remainder, ergo divisible)

>>8600377
Im not sure and neither have I ever seen anyone talk about it, but I'd assume itd be good because they see how you problem solve in general

I did the first one and is pretty simple, but I don't know if loops are supposed to be used or if there is some very clever way of doing it.


Currently on problem 2 and thinking of a pretty solution rather than recursively brute forcing the answer. Trying to explore if there is some sort of pattern to exploit

Yes there are tricks

Not having to use a loop means better O(log)

I've done the first 11. None have required particularly advanced math concepts yet. Just logic.

I meant for finding how many numbers that 3/5/15 are multiples of, but I just realize I was a potato and didn't do floor division lol

It starts getting into probability and other real math at around problem 300+

The first 1-20 questions are good for learning a new language and getting in practice as they aren't that difficult, there's also this http://exercism.io/ and https://leetcode.com/

Do it in MATLAB and you don't have to know jack shit.

Its nice to learn something and do something for the exercise not just get the answer.

How long did that take you?
