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].
UPDATE (2016/2/13):
The return format had been changed to zero-based indices. Please read the above updated description carefully.

Leetcode.com is restricting one session only in the same time, which means if you have login same account otherwhere, the existing login session will be expired immediately. This will greatly harm your experience since you have to re-login again and again among different sessions.
However leetcode-cli will help some one this.It will try to save you from this trial and re-login transparently without interrupting your current work whenever it notices the session is already expired. To enable this in your config:
"AUTO_LOGIN": true
NOTE: if enabled, your PASSWORD will be persisted locally to achieve auto login, so PLEASE be careful to ONLY enable this on your OWN computer for the sake of security!
