# I got right answer ,but OJ gave me the Status 'Time Limit Exceeded' .

• It must have more efficient way for this question by using JavaScript.
Can someone help me ? : )

• of course it causes time exceed, your time complexity is O(n^2), you should use hashmap or dic to solve this problem.

• I am a novice , I have encountered the same problem.
Submission Result: Time Limit Exceeded
