Instructions

1. Write rollCallDwarves:(NSArray *)dwarves. This method should take in an NSArray of dwarves and returns a roll call sheet with their number. I'd recommend using a standard for loop for this. This is a roll call sheet for HUMANS so please start counting at 1. For example given the following array:

@[@"Doc",@"Dopey",@"Bashful"]

return an NSMutableString that looks like this:

1. Doc | 2. Dopey | 3. Bashful

2. Write the summonCaptainPlanet:(NSArray *)planteerCalls method. This method should take an NSArray of forces. These forces a bit lackluster...let's give them some hart and make them all caps and an exclamation point after to show we really mean it! Return another NSArray with a capitalized and exclamation point after. So for example the following NSArray:

@[@"earth",@"wind"]

would turn into:

@[@"EARTH!", @"WIND!"]

3. Write the longPlaneteerCalls:(NSArray *)planteerCalls method. The planeteer calls are supposed to be short so let's find out if any of our calls have more than 4 characters. This method takes in a list of planteerCalls and returns the list of planeteer calls that have more then 4 characters. So for example the following NSArray:

@[@"earth",@"wind"]

would return:

@[@"earth"]

4. Write the findTheCheese:(NSArrray *)cheeses method. This method should look through the NSArray of NSStrings and find the first string that matches one of the following cheese strings: @"cheddar", @"gouda", or @"cambert". It should then return the NSString of the resulting search. If it doesn't find anything, return nil.

5. Write the calculateDollarAmountsWithReceipt:(NSArray *)receipt method. This method should keep help someone keep track of their money. Sadly...people keep their receipts in a weird way. They keep in them in an NSArray that looks like this:

@[@"$$", @"$", @"$$$"]

So this method takes an array like that in, and should return another array converted to monetary values (As NSString) So the previous NSArray would turn into this:

@[@"$2",@"$1",@"$3"]
