arrays - Swift:HackerRank readLine 一个 Int 数组

Question

我正在玩 HackerRank。我需要从行读取整数数组的问题之一:

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

我尝试过:

let line = readLine()
print(line)

但我收到此错误:

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

你们中有人知道我应该如何读取行并获取数组吗？

非常感谢您的帮助

Answer 1

let line = readLine()!

print(line)

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