相互添加两个数组的元素 [英] Add elements of two array with each other

问题描述

我有2个Int类型的数组

I have 2 Array of type Int like this

let arrayFirst = [1,2,7,9]
let arraySecond = [4,5,17,20]

我想添加元素每个数组，如arrayFirst [0] + arraySecond [0]，arrayFirst [1] + arraySecond [1]等等，并将其分配给另一个数组，因此数组的结果将类似于

I want to add the elements of each array, like arrayFirst[0] + arraySecond[0], arrayFirst[1] + arraySecond[1] an so on and assign it to another array, so the result of the array would be like

[5,7,24,29]

[5, 7, 24, 29]

什么是使用 swift3实现此目的的最佳实践

推荐答案

您可以添加两者像这样的数组

You can add both the arrays like this

let arrayFirst = [1,2,7,9]
let arraySecond = [4,5,17,20]

let result = zip(arrayFirst, arraySecond).map(+)
print(result)
