Two Sum

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, and you may not use the same element twice.

Example:

Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].
java编码：

class Solution {
    public int[] twoSum(int[] nums, int target) {
        
        for(int i = 0;i < nums.length ; i++){
            for(int j = i+1;j<nums.length ;j++){
                
                target = nums[i]+nums[j];
                if(target==9){
                    return i ,j;
                }
                
            }
            
        }
        
        
    }
}
