[Swift] Codility Lesson 5 - CountDiv
๋ฌธ์ Write a function: public func solution(_ A : Int, _ B : Int, _ K : Int) -> Int that, given three integers A, B and K, returns the number of integers within the range [A..B] that are divisible by K, i.e.: { i : A ≤ i ≤ B, i mod K = 0 } For example, for A = 6, B = 11 and K = 2, your function should return 3, because there are three numbers divisible by 2 within the range [6..11], namely 6, 8 an..

[Swift] Codility Lesson 4 - MissingInteger
๋ฌธ์ This is a demo task. Write a function: public func solution(_ A : inout [Int]) -> Int that, given an array A of N integers, returns the smallest positive integer (greater than 0) that does not occur in A. For example, given A = [1, 3, 6, 4, 1, 2], the function should return 5. Given A = [1, 2, 3], the function should return 4. Given A = [−1, −3], the function should return 1. Write an efficie..
