我正在学习本书的第一章，但无法弄清楚实验:

Add another variable to keep track of which kind of number was the largest, as well as what that largest number was.

这是书中的代码:

let interstingNumbers = [
"Prime": [2, 3, 5, 7, 11, 13, 17],
"Fibonacci": [1, 1, 2, 3, 5, 8],
"Square": [1, 4, 9, 16, 25, 36],
]
var largest = 0
for (kind, numbers) in interstingNumbers {
    for number in numbers {
        if number > largest {
            largest = number
        }
    }
}
largest

最佳答案

像这样:

let interstingNumbers = [
"Prime": [2, 3, 5, 7, 11, 13, 17],
"Fibonacci": [1, 1, 2, 3, 5, 8],
"Square": [1, 4, 9, 16, 25, 36],
]
var largest = 0
var largestKind = ""
for (kind, numbers) in interstingNumbers {
    for number in numbers {
        if number > largest {
            largest = number
            largestKind = kind
        }
    }
}
largest
largestKind
