RE: Project Euler Solutions - Legofreak - 07-06-2015

I tried this for the first time today... I don't know any programming languages so I used scratch...

problem #1
[Image: euler%201_zpsw5injp9l.png]

I have a feeling I won't be solving any more of these...

edit:

took me long enough to figure out how to determine if something is even or odd...
problem #2
[Image: euler%202_zps2u5dn4uv.png]

and I figured out problem #5 on a calculator

jesus it's probably better to use a calculator than this (i'm sure the first 20 are possible with only calculator)

I can't stop doing these problems

They're just too interesting, too intriguing

So I found myself installing Python and Sublime Text again to revive my Project Euler account. Project one solution:

Code:
x = 1
sol = 0
while x < 1000:
    m = x % 3
    if m == 0:
        sol += x
    else:
        m = x % 5
        if m == 0:
            sol += x
    x += 1
print(sol)
Pretty tiny for me actually! Only 12 lines of code! I bet you can do it with less, but that's actually fine for me!

And I made the second one first try!

Code:
x = 1
y = 1
s = 0
while x + y < 4000000 and x + y * 2 < 4000000:
    x += y
    if x % 2 == 0:
        s += x
    y += x
    if y % 2 == 0:
        s += y
if x + y < 4000000:
    x += y
    if x % 2 == 0:
        s += x
    print(s)
else:
    print(s)

#1 in Python
Code:
sum([ x for x in range 1000 if (x % 3==0) | (x % 5 == 0)])

edit: even smaller

RE: Project Euler Solutions - jxu - 01-24-2016

Reduce is unnecessary (and deprecated in Python 3). sum() does the trick
