Question

我正在上一个有关Swift编程的动手实践课程，将我重定向到Hackerrank

编写一个名为printMessage的函数，该函数带有两个参数-字符串消息和整数计数。该消息应打印并按照count参数中指定的内容重复该消息。

消息：“你好，你好吗”

例如，以Count为8

这应该连续打印8条消息：“你好，你好”。

问题是当我提交我的代码时总是说错误答案，然后我尝试使用自定义输入，并且在STDOUT上没有响应。有人知道怎么了吗？

import Foundation 

func printMessage(message: String, count: Int) {

    for _ in 0..<count {
        print(message)

    }
}

let message: String = readLine()!
let count: Int = Int(readLine()!)!
printMessage(message: message, count: count)

Answer 1

在一些快速练习中，Hackerrank会在缓冲区溢出时触发该消息，而不是警告您

Answer 2

我以前遇到过这个问题，我解决它的方法是将代码保存在某个地方并重置为样板代码。因此，只需重置为样板并重新复制功能即可。在许多迅速的hackerrank问题上，它们具有以下内容：

函数后的代码是写到stdout的代码

HackerRank说〜对stdout无反应〜Swift
