力扣：两数之和

class Solution {
    public int[] twoSum(int[] nums, int target) {
        int[] arr = new int[2];
        for(int i = 0 ; i < nums.length ; i++){
            for(int j = i+1 ; j < nums.length ; j++){
                if(target==nums[i]+nums[j]){
                    arr[0] = i ;
                    arr[1] = j ;
                }
            }
        }
        return arr ;
    }
}
