LeetCode 1. 两数之和(swift)

示例 1：

输入：nums = [2,7,11,15], target = 9
输出：[0,1]
解释：因为 nums[0] + nums[1] == 9 ，返回 [0, 1] 。
示例 2：

输入：nums = [3,2,4], target = 6
输出：[1,2]
示例 3：

输入：nums = [3,3], target = 6
输出：[0,1]

class Solution {
    func twoSum(_ nums: [Int], _ target: Int) -> [Int] {
        var dic: [Int: Int] = [:]
        for (index, value) in nums.enumerated() {
            let reminder: Int = target - value
            print(reminder)
            print(dic)
            if dic.keys.contains(reminder) {
                if let reminderIndex = dic[reminder],reminderIndex != index  {
                    return [reminderIndex, index]
                }
            }
            dic[value] = index
        }
        return []
    }
