Two Sum. Easy. 56.8K. Ln 1, Col 1. Case 1. Case 2. Case 3. nums = [2,7,11,15] target = 9. Source. Can you solve this real interview question? Two Sum - Level up your coding skills and quickly land a job. This is the best place to expand your knowledge and get prepared for your next interview.
Run a loop to maintain the first index of the solution in the array. Run another loop to maintain a second index of the solution for every first integer. If at any point, the sum of values of two indices is equal to the target. Print its indices.
class Solution { public: vector<int> twoSum(vector<int>& nums, int target) { unordered_map<int, int> numToIndex; for (int i = 0; i < nums.size(); ++i) { if (const auto it = numToIndex.find(target - nums[i]); it != numToIndex.cend()) return {it->second, i}; numToIndex[nums[i]] = i; } throw; } };
Two Sum - 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.
Two Sum II - Input Array Is Sorted. Medium. Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order, find two numbers such that they add up to a specific target number. Let these two numbers be numbers[index 1] and numbers[index 2] where 1 <= index 1 < index 2 <= numbers.length.
