Objective-C rulez! :)

Objective-C rulez! :)

Nice to talk to a clever man

Oh, yeah

SPOJ THINKBIT

Well, I always got "compilation error" or "wrong answer" in THIS.
Here are my solutions that works OK on my local machine but NOT on the SPOJ!

return 2 | !(!(x >> 1)); // I like this one!
// but they don't wanna bit shifts!

return 2 | !(!((x & 2) | (x & 4) | (x & 8) | (x & 16) | (x & 32) | (x & 64) | 
(x & 128) | (x & 256) | (x & 512) | (x & 1024) | (x & 2048) | (x & 4096))); 
// kinda idiotic, but works :)

return 2 | !(!(x & 1073741822)); // OK on 64-bit UNIX

return 2 | !(!(x & 65534)); // 32-bit? here it is...

return 2 | !(!(x & 4094)); // WTF?! this gives "wrong answer" on this f... SPOJ !

Whats wrong with SPOJ guys?

SPOJ THINK

Strange Pattern (Easy)

return 3-(x%2)/x; // OK!

return -!(x-1)+3; //gives a "compilation error" ;)

THE BLIN! As expressive as BLYAD but you can also eat it!

The Objective-C religion doesn't allow to insert Integers into NSDictionary

So...

// why they've done so with old good enums?
typedef NS_ENUM(NSUInteger, PaymentType) {
    tCreditCard  = 0,
    tBankAccount = 1,
    tBitcoin     = 2
};

        ...

NSDictionary *payItem = [[NSDictionary alloc] 
                        initWithObjectsAndKeys:[NSNumber numberWithInt:tCreditCard], @"type", 
                        [self makeFakeCreditCardData], @"data", nil];

        ...

switch([[object valueForKey:@"type"] integerValue])
{
    case tCreditCard:
        // do something
        break;

        ...

Thank you very much!

Linking Storyboards

Very "elegant" solution to resolve "We have one storyboard at all" iOS programmers group nightmare.

Yes, I'm making fun :)
