Two sum using two pointers java, 1️⃣ Pascal’s Triangle LeetCode 118 https://lnkd

Two sum using two pointers java, May 17, 2025 · 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. 1️⃣ Pascal’s Triangle LeetCode 118 https://lnkd. May 20, 2024 · This approach works by initializing two pointers, one at the beginning (left) and one at the end (right) of the array. Apr 23, 2025 · This method involves sorting the array and then using two pointers to identify a pair of numbers whose sum equals the target. Given a sorted array A (sorted in ascending order), having N integers, find if there exists any pair of elements (A [i], A [j]) such that their sum is equal to X. #2 Consistency of DSA 🚀 Today’s DSA practice focused on array patterns & two-pointer logic. By using pointers, we can process two elements per loop, instead of just one. in/gbt8PAz6 Approach Build row by row First 🚀 DSA Journey in Java – LeetCode 167 Solved! 🚀 Continuing my DSA journey in Java through the Apna College DSA Course, today I solved an important two-pointer problem: 📌 LeetCode 167 . We then move the pointers based on the sum of the elements at these pointers. 🧩 Problem Statement: Given an Nth Node from the End: Finding the Nth node from the end of the list, often using two pointers separated by N nodes. Common patterns in the two-pointer approach involve: Two pointers each starting from the beginning and the end until they both meet One pointer moves at a slow pace while the other pointer moves at a faster pace Both of the above patterns can help Array Operations in Java – Traversal, Insertion, Deletion, Searching | DSA for Beginners [With Code] Data Structure and Algorithm Patterns for LeetCode Interviews – Tutorial L1. See full list on hellokoding. Remove Duplicates from a Sorted Linked List: Iterating through a sorted list and removing nodes with the same value as their predecessor. Jul 23, 2025 · Two pointers is really an easy and effective technique which is typically used for searching pairs in a sorted array. com Apr 4, 2025 · In the two-pointer approach, pointers refer to an array’s indexes. Solved LeetCode Problem 15 – 3Sum Today, I solved LeetCode #15: 3Sum, a very popular and important problem based on sorting and two-pointer technique 🚀 The task was to find all unique Intuition (Based on My Code): I used two pointers: • low → start of the window • high → end of the window As high moves forward: • I add the character to the HashMap • The map stores 🚀 Day 10 of 100 Days of DSA 🔥 Solved: 3Sum Closest | Two Pointer Approach | Java Today I solved the classic 3Sum Closest problem using an optimized approach.
