Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution.
Example:
Given nums = [2, 7, 11, 15], target = 9,Because nums[0] + nums[1] = 2 + 7 = 9,return [0, 1].

package com.dengpf.TwoNumbers;/** * Created by kobe73er on 16/12/17. */public class Solution {    public int[] twoSum(int[] nums, int target) {        int[] indexs = new int[2];        int i = 0;        for (; i < nums.length; i++) {            int j = i + 1;            for (; j < nums.length;) {                if ((nums[i] + nums[j]) == target) {                    indexs[0] = i;                    indexs[1] = j;                    return indexs;                }                j++;            }        }        return indexs;    }    public static void main(String args[]) {        int[] nums = {-3,4,3,90};        Solution solution = new Solution();        int[] result = solution.twoSum(nums, 0);        for (int i = 0; i < result.length; i++) {            System.out.println(result[i]);        }    }}
