Beautiful Days at the Movies

    This was my solution in Swift

    import Foundation

// Complete the beautifulDays function below.
func beautifulDays(i: Int, j: Int, k: Int) -> Int {
    var count = 0

    for value in i...j {
        var r = value
        var q = 0
        while r > 0 {
            q = q * 10 + r % 10
            r /= 10
        }
        abs(value - q) % k == 0 ? count += 1 : ()
    }
    return count
}
