Coding interviews are tough. But fortunately, there's a tried and proven method to get better at them. With a combination of studying, practicing questions and doing mock interviews, getting that dream job can become a reality.

* Decide on a programming language
* Study CS fundamentals
* Practice solving algorithm questions
* Internalize the Do's and Don'ts of interviews
* Know what signals and behaviours interviewers are looking out for
* Practice doing mock interviews
* Interview successfully to get the job

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

You can return the answer in any order.



Example 1:

Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Output: Because nums[0] + nums[1] == 9, we return [0, 1].

Example 2:

Input: nums = [3,2,4], target = 6
Output: [1,2]


Example 3:

Input: nums = [3,3], target = 6
Output: [0,1]


Constraints:

2 <= nums.length <= 103
-109 <= nums[i] <= 109
-109 <= target <= 109

Only one valid answer exists.

Solution will be provided tomorrow.
