Swift:HackerRank readLine一个Int数组 [英] Swift: HackerRank readLine an array of Int

问题描述

我在玩HackerRank.我需要从行到整数数组读取的问题之一:

I'm playing with HackerRank. One of the problems I need to read from line to arrays of Integers:

A=(1,2,3)
B=(1,4,7)

我尝试过:

let line = readLine()
print(line)

但是我得到这个错误:

solution.swift:2:7: warning: expression implicitly coerced from 'String?' to Any
print(line)
      ^~~~
solution.swift:2:7: note: provide a default value to avoid this warning
print(line)
      ^~~~
           ?? <#default value#>
solution.swift:2:7: note: force-unwrap the value to avoid this warning
print(line)
      ^~~~
          !
solution.swift:2:7: note: explicitly cast to Any with 'as Any' to silence this warning
print(line)
      ^~~~
           as Any

你们中的任何人都知道我应该如何读取行并获取数组吗?

Any of you knows how I suppose to read line and get the array?

非常感谢您的帮助

推荐答案

let line = readLine()!

print(line)

//To Array, should work. Wrote it real quick
let array = readLine()!.characters.split(" ").map( { String($0)! } )
