代码实现

public static int[] twoSum(int[] nums, int target) {
        int[] res = new int[2];
        for (int i = 0; i < nums.length-1; i++) {
            int temp = target - nums[i];
            for (int j = i+1 ; j < nums.length; j++) {
                if (nums[j] == temp) {
                    res[0] = i;
                    res[1] = j;
                    break;
                }
            }
        }
        return res;
    }
