两数之和

Go

func twoSum(nums []int, target int) []int {
    m := make(map[int]int)
    var res []int = []int{0,0}
    for num,value := range nums {
        diff := target - value
        if _ ,ok := m[diff];ok {
            res[0] = m[diff]
            res[1] = num
        }
        m[value] = num
    }
    return res
}
