LeetCode #1Two 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.

Example:

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

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

class Solution {
    public int[] twoSum(int[] nums, int target) {
        int []result=new int[2];
        Map<Integer,Integer> map=new HashMap<Integer,Integer>();
        for(int i=0;i<nums.length;i++){
            if(map.containsKey(target-nums[i])){
                result[1]=i;
                result[0]=map.get(target-nums[i]);
            }
            
            map.put(nums[i],i);
            
            
        }
        return result;
        
    }
}
