大四才开始看算法，是不是已经晚了？算法渣渣的开始
题目是这样的：
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].
我的代码是这样的：
public class Solution {
public int[] twoSum(int[] nums, int target) {
int sum[]=new int[2];
for(int i=0;i<nums.length;i++){
for(int j=1;j<nums.length;j++){
if(nums[j]+nums[i]==target){
sum[0]=j;
sum[1]=i;
}
}
}
return sum;
}
}
系统说通过了一半的测试，例如[3,3]6输入就会出错
不是很明白，感觉我的答案和其他的也差不多
