[1] Two Sum    	(File: two-sum.cpp)

* algorithms
* Easy (25.6%)
* Total Accepted: 274880
* Total Submissions: 1074257
* Testcase Example:  '[3,2,4]\n6'

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.

Only show the code template:

$ leetcode show -t --no-desc 1
class Solution {
public:
	vector<int> twoSum(vector<int>& nums, int target) {

	}
};

star

Mark your favorite problems. The starred problem will be shown with a ★.

  • -d to unstar.
  • Instead of index number, you can use name to star a problem.
    • leetcode star "Two Sum"
    • leetcode star two-sum

Example

$ leetcode star 1
[1] Two Sum ★

$ leetcode star 1 -d
[1] Two Sum ☆

stat

Show your personal statistics of the problems progress.

  • -g to show the heatmap graph.
  • -t to show statistics on given tag. E.g.
    • algorithms
    • database
    • shell
