Two Sum
EasyAcceptance Rate 49.2%
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.Examples
Example 1
Input
nums = [2,7,11,15], target = 9
Output
[0,1]
Explanation
Because nums[0] + nums[1] == 9, we return [0, 1].
Constraints
2 <= nums.length <= 10^4-10^9 <= nums[i] <= 10^9-10^9 <= target <= 10^9Only one valid answer exists.
