在数组中找到 2 个数之和等于给定值的数字，结果返回 2 个数字在数组中的下标

go代码

package main

import "fmt"

func twoSum(source []int, target int) []int {
	var resultArray []int
	for start := 0; start < len(source)-1; start++ {
		max := len(source) - 1
		for start < max {
			if source[start]+source[max] == target {
				resultArray = append(resultArray, start, max)
				break
			} else {
				max--
			}
		}
	}
	return resultArray
}

func main() {
	source := []int{2, 3, 5, 7, 9}
	const TARGET = 8
	sum := twoSum(source, TARGET)
	fmt.Printf("数组source:%d,任意两数和为target:%d的下标分别为:%d", source, TARGET, sum)
}
