@Optimizer Fallout 1, 2, 3, and 4 all have metacritic scores of 85-93, and the latter 2 are on the higher end. Compare with Halo 1 which score 97, followed by sequels that slowly dropped to 87 with Halo 4 and 85 with Halo 5.

@MartinBüttner I just want to learn about how it works and might include that in the post

Thanks!

@MartinBüttner now that we have the list, I need the code to take in a number n and return the nth square of square number...the 1st square of square number must be 7, can you do that?

Martin Büttner

I'm not sure I understand what you're asking. Are you sure it wouldn't be easier to reimplement it in a language you know yourself? ;)

The code is basically a recursive function which iterates over all partitions of a number and returns True if one of them yields only perfect squares.

TanMath

8:56 PM

@MartinBüttner well I am not sure how to implement it ... I found this code and thought I could edit it to work for the challenge...

Martin Büttner

@TanMath what language(s) are you comfortable with?

TanMath

@MartinBüttner python...

let me write up some pseudocode that looks a bit more like python

@MartinBüttner thank you...

def r(n,digits):
    z = len(digits)
    if z < 1:
        return True
    else:
        i = 1
        while i < z:
            t = to_integer(digits[:i])
            if is_integer(sqrt(t)) and t < n and r(n,digits[i:]):
                return True
        return False

@TanMath ^ this would be a function that takes an integer and a list of its digits (or a string representation of the integer) and tells you if that integer fits your criteria

that is, this one gives the squares

so r(49,"49") would yield True

TanMath

@MartinBüttner so if I want to find the 4th square number now would I do that?

quartata

@MartinBüttner This is a really interesting language.

Martin Büttner

thank you :)

quartata

I wonder if I should sacrifice an entire day and try to do FizzBuzz in it

Martin Büttner

you should.

TanMath

Would I have to go through all the integers unt I get four trues?

quartata

@MartinBüttner I see.

Martin Büttner

@TanMath yes... well you'd have to go through the square numbers only, of course

(that's what the mathematica code does as well)

quartata

9:08 PM

Of course, I probably shouldn't take your word for it...

Martin Büttner

you should.

TanMath

@MartinBüttner OK.. Thanks a lot! I am so grateful for your help and support...

Martin Büttner

no problem

a faster solution would actually just enumerate tuples of squares and concatenate them, but it will be much trickier to get them in the correct order.

can someone please teach me the syntax for if expressions in CJam? I'm learning and trying to do the fizz buzz program

quartata

Well, I have my first ever TwistScript program: WG

It transpiles to this:

]J[n/#
SU

Which outputs 10 in GolfScript.

I have no idea why it does, but it is the first program that didn't throw an error.

Faraz Masroor

quartata maybe you can help me

you know cjam right?

quartata

@FarazMasroor Whatcha need?

Faraz Masroor

10:14 PM

how do you do if statements? Is it '{test}{statement}?' ? w/o quotes

quartata

Basically, you want to push the result you want to check to the stack in some way first

So maybe 2 2=

Then do {expression}&

Faraz Masroor

so my program is this 1{_1000<}{{_2%0=}{"Fizz"o}?{_3%0=}{"Buzz"o}?}w

quartata

Sorry I got that mixed up.

You use &.

Faraz Masroor

oh wait hang on i forgot to increment!

so it would be {_2%0=}&{"Fizz"o} then the same for 3

how do you do if-else statements?

Faraz Masroor

so how do you set up the if part in that, like wheres the condition and where are the two actions to do

quartata

10:27 PM

{this is the if part}{this is the else part}?

As it turns out my TwistScript interpreter is bugged and I'm not sure why

Faraz Masroor

so for the fizz program, lets say its not fizzbuzz but only fizz so modulo 2

quartata

@FarazMasroor You mean mod 3, right?

Faraz Masroor

so i would say {_2%0=}{"Fizz"o}? if we ignore the modulo 3 part of fizzbuzz

quartata

Fizz is mod 3, Buzz is mod 5. Just so you know.

Faraz Masroor

oh well now its 2 and no 3 nor 5

would my snippet be correct?

quartata

10:30 PM

Why do you have the beginning part in {}?

Alex A.

TIL the Apple Developer Program costs $99 USD/year and you only get 70% of the revenue generated from paid apps you post to the App Store. ಠ_ಠ

quartata

I think it should just be 2%{"Fizz"}{whatever}?

@AlexA. Yeah, it's kind of absurd.

I can't believe people develop apps for iOS, much less free ones.

Faraz Masroor

oh

so 0 and 1 are truthy and you don't need to put the if statement in brackets

like the condition doesnt need to be in bracktets

Alex A.

@quartata Why wouldn't people develop iOS apps? The iPhone has very large share of the smartphone market, and I would be surprised if the iPad doesn't have the majority share of the tablet market. Developing paid iOS apps is potentially profitable.

Developing free ones is a good way to increase your visibility as a developer, though there's no return on investment.

(Unless you include ads or something)

I'm not personally interested in developing mobile apps but I can see why people would do it.
