project euler dominated :o

Re: The Project Euler thread

lucked out getting the Perfection badge just in time... this new one is a doozy.

383 looks easy as ****
EDIT: as of 5:29 i have a formula for T5(5^n)
EDIT: as of 5:38 i have a general formula for T5(n)... sorta
EDIT: BAM

the most coding i did was with spreadsheets and i found the answer about 2 hours from starting work on it

Re: The Project Euler thread

Haven't even looked at 383 yet... tried 382 for a bit and couldn't solve it, so I took a break, haha.

Re: The Project Euler thread

Decided to try 383. Got a working approach for T5(n) very quickly but I don't think it's scalable yet

EDIT: Figured out T5(5^n)

Re: The Project Euler thread

I'm working on 383 too. I got a formula for f5(n!) but nothing for T5(n) yet :(

Re: The Project Euler thread

Just gotta knock back 382 and that's that
Not really a fan of recurrence-relation problems but meh

Re: The Project Euler thread

Weeee, got it -- 100% again

Re: The Project Euler thread

390 should be ok, but I am fearing 391. it's likely going to be brutal

[Reincarnate]

Re: The Project Euler thread

I've got a program that will solve for M(n) but is not scalable to higher levels

You know it's a tough problem when very few of the usual heavy hitters have solved it, even 24 hours after its release.

Re: The Project Euler thread

391 solved, back to 100%. That one was tricky.

Re: The Project Euler thread

Until 392..

Re: The Project Euler thread

So I'm teaching myself BASIC and I figure that this would be a good way to learn
Unfortunately, I can't even solve problem 1 because I'm a dumb shit rofl (I could solve on paper, but that'd take forever)

There's something wrong with my code.
Don't hate, I haven't touched a programming language since high school (so 2008)

count = 0
addNumber = 0
a$ = ""

[loop]
count = count + 1
if (count mod 3 = 0) or (count mod 5 = 0) then
addNumber = addNumber + count
print "Count = "; count
print "addNumber ="; addNumber
else
print "Count = "; count
print "addNumber ="; addNumber
end if

if count < 1000 then
goto [loop]
else
print addNumber
end if
stop

Some info regarding my code:
The a$ was a variable I used to make the code stop during the first if-then statement. It originally looked like this:

print "Count = "; count
print "addNumber ="; addNumber
print "press any button and enter to continue"
input a$
else

I know using goto makes me look like a newb programmer, but that's fine. I'm not too keen on streamlining my code just yet.

Re: The Project Euler thread

Shit, I think I know what's wrong with my code. 2 mod 3 would end being 0. So it's adding to addNumber before it should be.

Re: The Project Euler thread

2 mod 3 is 2

(x mod y is the remainder of x / y)

PS use Python instead, it's cooler

sumTotal = 0
num = 1
while num < 1000:
if (num % 3 == 0) or (num % 5 == 0):
sumTotal = sumTotal + num
num = num + 1
print sumTotal

Damn thing doesn't save formatting but w/e
