考场上没啥纠结的，直接双循环暴力解决 也可以拿到分！注意数组下标就行了

 public int[] twoSum (int[] numbers, int target) {
        // write code here
        int [] twoindex = new int[2];
        for(int i = 0;i<numbers.length-1;i++){
            for(int j = i+1;j<numbers.length;j++){
                if((numbers[i]+numbers[j])==target){
                    twoindex[0]=i+1;
                    twoindex[1]=j+1;
                    return twoindex;
                }
            }
        }


        return null;
    }
