}

Here is my solution in Python 3!

def countApplesAndOranges(s, t, a, b, apples, oranges):
    print(len(list(filter(lambda x: s<=x<=t, [a+p for p in apples]))))
    print(len(list(filter(lambda x: s<=x<=t, [b+p for p in oranges]))))

func countApplesAndOranges(s: Int, t: Int, a: Int, b: Int, apples: [Int], oranges: [Int]) -> Void {
    // Write your code here
    print(apples.filter { s...t ~= ($0 + a)}.count)
    print(oranges.filter { s...t ~= ($0 + b)}.count)    
}

Swifty way of doing better things.
