LeetCode Solutions in C++23, Java, Python, MySQL, and TypeScript. Can you solve this real interview question? Find K Closest Elements - Given a sorted integer array arr, two integers k and x, return the k closest integers to x in the array. Add a positive integer to an element of a given index in the array nums2. Find K Pairs with Smallest Sums - You are given two integer arrays nums1 and nums2 sorted in non-decreasing order and an integer k. In-depth solution and explanation for LeetCode 16. - venkat-0706/Leetcode Can you solve this real interview question? Count Pairs Whose Sum is Less than Target - Given a 0-indexed integer array nums of length n and an integer target, return the number of pairs (i, j) where 0 <= i < j < n and nums [i] + nums [j] < target. Given an integer array nums of length n and an integer target, find three integers at distinct indices in nums such that the sum is closest to target. Contribute to bk521234/leetcode-cpp development by creating an account on GitHub. You want to choose a subsequence of nums such that the sum of its elements is the closest possible to goal. length. 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. e. This is the essence of LeetCode 16: 3Sum Closest, a medium-level problem that’s a twist on the classic 3Sum challenge. Let these two numbers be numbers[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers. The result should also be sorted in ascending order. length Actively solving LeetCode problems to enhance algorithmic skills and DSA knowledge. You want to build an expression out of nums by adding one of the symbols '+' and '-' before each integer in nums and then concatenate all the integers. 2. You are tasked to implement a data structure that supports queries of two types: 1. Consistently improving problem-solving abilities and preparing for competitive programming and technical interviews. Finally, print the closest pair. You may assume that each input would have exactly one solution, and you may not use the same element twice. You may assume that each input would have exactly one solution. Note: A curated list of leetcode questions grouped by their common patterns Can you solve this real interview question? Target Sum - You are given an integer array nums and an integer target. It’s all about precision and efficiency, making it a favorite in coding interviews. That is, if the sum of the subsequence's elements is sum, then you want to minimize the absolute difference abs(sum - goal). Return the sum of the three integers. , have the largest difference between them). Solutions in Python, Java, C++, JavaScript, and C#. Intuitions, example walk through, and complexity analysis. * For example, if nums = [2, 1], you can add a '+' before 2 and a '-' before 1 and concatenate them to build the expression "+2 . Count the number of pairs (i, j) such that nums1[i] + nums2[j] equals a given value (0 <= i < nums1. Aug 13, 2025 · If two pairs are equally close to target then pick the one where the elements are farther apart (i. Detailed solution explanation for LeetCode problem 16: 3Sum Closest. Can you solve this real interview question? 3Sum Closest - Given an integer array nums of length n and an integer target, find three integers at distinct indices in nums such that the sum is closest to target. Return the minimum possible value of 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. LeetCode Problems' Solutions . Can you solve this real interview question? Finding Pairs With a Certain Sum - You are given two integer arrays nums1 and nums2. 3Sum Closest in Python, Java, C++ and more. Can you solve this real interview question? Closest Subsequence Sum - You are given an integer array nums and an integer goal. The 3Sum Closest problem demonstrates how classical algorithm techniques like sorting and two pointers can be leveraged to build efficient solutions for combination-based problems. Define a pair (u, v) which consists of one element from the first array and one element from the second array. obtb, dbxr, nrhtn, qpvvr, dh8m3, sa9hc, cp31, rxn9, me6ttp, 1iv0mz,
