class strcollector {
    var bin:[Character]
    var count:Int
    init() {
        self.bin = [Character]()
        self.count = 0
    }
    func collect(feed:String) {
        let chars = feed.characters
        for elem in chars {
            self.bin.append(elem)
            self.count++
        }
    }

    func getchars() ->[Character] {
        return self.bin
    }
}
