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] Explanation: 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 <= 104
-109 <= nums[i] <= 109
-109 <= target <= 109
- Only one valid answer exists.
Solution
class Solution { /** * @param Integer[] $nums * @param Integer $target * @return Integer[] */ function twoSum($nums, $target) { $result = 0; for( $i = 0; $i < count($nums); $i++ ) { for( $j = $i+1; $j < count($nums); $j++) { $result = $nums[$i] + $nums[$j]; if( $result == $target ) { return [$i, $j]; } } } } }
