Swift解这种类型的题，就是耍流氓

while let short = readLine(), let long = readLine() {
    var s1 = Set<Character>()
    var s2 = Set<Character>()
    for c in short {
        s1.insert(c)
    }
    for c in long {
        s2.insert(c)
    }
    let a1 = s1.sorted().map({ String($0) }).joined()
    let a2 = s2.sorted().map({ String($0) }).joined()
    var ret = true
    for c in a1 {
        if !a2.contains(c) {
            ret = false
            break
        }
    }
    print(ret)
}
