Question

having trouble with the following swift 5 problem. It is just printing the number 4 twice and it seems to be ignoring camelCasePhraseTwo, please help if you can:

/* Problem 4

Write a function that takes in a camel-case string and returns an integer representing the number of words in the string

Notes:

- Assume all input will contain only letters, and the string will be a valid camel-cased phrase

- Do not loop through the array manually.

*/

func camelCaseWordCount(for camelCasePhrase: String) -> Int{

var camelCasePhraseOneCount: Int = 1

var camelCasePhraseTwoCount: Int = 1

let lowercase: Set<Character> = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

camelCasePhraseOne.removeAll(where: { lowercase.contains($0) })

camelCasePhraseTwo.removeAll(where: { lowercase.contains($0) })

camelCasePhraseOneCount = camelCasePhraseOne.count

camelCasePhraseTwoCount = camelCasePhraseTwo.count

return camelCasePhraseOneCount + 1

return camelCasePhraseTwoCount

}

//// Sample Input

var camelCasePhraseOne = "camelCasePhraseOne"

var camelCasePhraseTwo = "aMuchLongerCamelCasePhraseThatIsWayWayWayMoreFunToTest"

//

//// Sample Output

print(camelCaseWordCount(for: camelCasePhraseOne)) // 4

print(camelCaseWordCount(for: camelCasePhraseTwo)) // 15

Answer 1

func camelCaseWordCount(for camelCasePhrase: String) -> Int{

var camelCasePhraseCount: Int = 1

var phrase:String=camelCasePhrase

let lowercase: Set<Character> = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

phrase.removeAll(where: { lowercase.contains($0) })

camelCasePhraseCount=phrase.count

return camelCasePhraseCount + 1

}

//// Sample Input

var camelCasePhraseOne = "camelCasePhraseOne"

var camelCasePhraseTwo = "aMuchLongerCamelCasePhraseThatIsWayWayWayMoreFunToTest"

//

//// Sample Output

print(camelCaseWordCount(for: camelCasePhraseOne)) // 4

print(camelCaseWordCount(for: camelCasePhraseTwo)) // 15

Output
