Two sum sorted, Best Time to Buy & Sell Stock 3. Two Sum Sorted - Why It Works - Arrays & Prefix Sums | Data Proof sketch Because the array is sorted, we can use two pointers to adjust the sum efficiently. Two Sum II - Input Array Is Sorted - 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. Solve Two Sum on sorted arrays with two-pointer technique - step-by-step visual walkthrough. Longest Substring Without Repeating Characters 7. Then for each element, we compute the required complement (i. They can: • Move toward each other • Move in the same direction (slow & fast) • Expand and contract (sliding style) Example: Problem → Find if a sorted array has two numbers that sum to . We can maintain two pointers, left = 0 and right = n - 1, and calculate their sum S = arr [left] + arr [right]. , target - arr [i]) and perform binary search on the remaining subarray (from index i+1 to end) to find that complement. You are given two integer arrays nums1 and nums2, sorted in non-decreasing order, and two integers m and n, representing the number of elements in nums1 and nums2 respectively. Given a sorted array of integers and a target sum, find two numbers such that they add up to the target. Remove Duplicates from Sorted Array 9. Container With Most Water 11. Maximum Sum Subarray of Size K 6. Aug 25, 2025 · The problem can be solved using two pointers technique. Contains Duplicate Sliding Window 5. Problem - Two Sum Sorted. Your task is to find two numbers in this array that add up to a specific target value. Step By Step Implementation: Sort the array in non-decreasing order. Jul 15, 2025 · Problem Statement: 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. If the current sum is too big, moving the right pointer left makes the sum smaller. Merge nums1 and nums2 into a single array sorted in non-decreasing order. Can you solve this real interview question? Two Sum II - Input Array Is Sorted - 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[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers. Move Zeroes 10. Return the indices of the two numbers, index1 Jul 26, 2025 · To check if a pair with a given sum exists in the array, we first sort the array. You are given a 1-indexed array of integers called numbers that is already sorted in non-decreasing order (smallest to largest). e. Classic two pointers. length. Return the indices (1-inde Clean solution function twoSum(numbers, target) left := 0 right := length of numbers - 1 while left < right sum := numbers[left] + numbers[right] if sum = target return [left + 1, right + 1] // 1-indexed else if sum < target left := left + 1 else right := right - 1 return [] // no solution found Feb 21, 2026 · Two Sum 2.
