Two sum ii input array is sorted gfg practice. If we know the position of one of the elements, do we also know the positioning of all the duplicate elements? Day 35 of DSA Practice #gfg160 Problem: Kth Missing Positive Number in a Sorted Array (GFG – Medium) Solved by iterating through the array and adjusting the value of k based on the missing Day 7 of Daily DSA 🚀 Solved LeetCode 167: Two Sum II – Input Array Is Sorted Approach: Used the two-pointer technique leveraging the sorted nature of the array. 167. Return the indices of the two numbers, index1 Pairs with given sum in doubly linked list All pairs with a given sum in two unsorted arrays Count pairs with absolute difference equal to k 2Sum on Sorted Input When the input is sorted, we can take advantage of the order to find the solution more efficiently. Better than official and forum solutions. Return the indices of the two numbers, index1 Day 42 of DSA Practice #gfg160 Problem: Two Sum – Pair with Given Sum (GFG – Easy) Solved using the two-pointer technique after sorting the array. Return the indices of the two numbers, index1 In-depth solution and explanation for LeetCode 167. Intuitions, example walk through, and complexity analysis. length. Let these two numbers be numbers[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers. 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. Nov 13, 2024 · Conclusion The 'Two Sum II - Input Array Is Sorted' problem can be solved with either a brute-force approach or the more efficient two-pointer technique. Approach: Sort the array Use two pointers Given an array arr [] of integers and another integer target. e. Using the two-pointer method takes full advantage of the sorted input array and leads to an optimal solution in terms of time and space complexity. Solutions in Python, Java, C++, JavaScript, and C#. Then for each element, we compute the required complement (i. Return the indices (1-indexed) of two numbers, [index1, index2], such that they add up to a given target number target and index1 < index2. 🟢 Two Sum II (167 Day 44 of DSA Practice #gfg160 Problem: Find All Triplets with Zero Sum (GFG – Medium) Solved the classic 3Sum problem by fixing two elements and using hashing to find the third required value To check if a pair with a given sum exists in the array, we first sort the array. Day 51 of DSA Practice #gfg160 Problem: Count All Triplets with Given Sum in Sorted Array (GFG – Medium) Solved using the Two Pointer Technique on a sorted array to efficiently count valid In this problem, the key point to focus on is the input array being sorted. Aug 25, 2025 · Given a 1-based indexed integer array arr [] that is sorted in non-decreasing order, along with an integer target. Given an integer array arr [] of size n, find the inversion count in the array. Two Sum II Input Array Is Sorted - Explanation Problem Link Description Given an array of integers numbers that is sorted in non-decreasing order. Note that index1 and index2 cannot be equal, therefore you may not use the same element twice. You are given a 1-based indexed integer array arr[] that is sorted in non-decreasing order, along with an integer target. , target - arr [i]) and perform binary search on the remaining subarray (from index i+1 to end) to find that complement. Your task is to find two elements in the array such that their sum is equal to target. Note: Inversion Count for an array indicates that how far (or close) the array is from being sorted. Determine if there exist two distinct indices such that the sum of their elements is equal to the target. If such a pair exists, return the indices 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. Instead of brute force, a more better approach" Two-Pointer Technique" can be used. As far as duplicate elements are concerned, what is their positioning in the array when the given array is sorted? Look at the image below for the answer. There Detailed solution explanation for LeetCode problem 167: Two Sum II - Input Array Is Sorted. . find two elements in the array such that their sum is equal to target. Day 54 of DSA Practice #gfg160 Problem: Pair with Given Sum in a Sorted Array (GFG – Easy) Approach: Use two pointers (left and right) since the array is already sorted Calculate the sum of arr 📌 LeetCode Practice Update Today I solved Two Sum II – Input Array is Sorted (167) and Intersection of Two Arrays (349) on LeetCode as part of my consistent DSA practice. Two array elements arr [i] and arr [j] form an inversion if arr [i] > arr [j] and i < j. Two Sum II - Input Array Is Sorted in Python, Java, C++ and more. iisq2, rq5akb, if42, oan3z, mxt9nm, c3bxx, biub4, yuiomb, zicb, 1058,
