If you’re tackling the LeetCode 18 Solution and working through the 4Sum problem, you’ve come to the right place! The 4Sum problem asks you to find all unique quadruplets (groups of four numbers) in an array that add up to a given target. It’s similar to the 2Sum and 3Sum problems but requires an approach that efficiently handles four numbers at a time. Let’s walk through how to solve this...
The LeetCode 16 Solution is a great way to improve your problem-solving skills on LeetCode by tackling the 3Sum Closest problem. This challenge requires you to find three numbers in an array that sum up to a value closest to a given target. While it may seem difficult at first, there’s an efficient approach that’s both easy to understand and implement. In this blog post, we’ll dive into the...
The “3Sum” problem, also known as LeetCode 15, is one of the most popular coding challenges in technical interviews. This problem requires finding unique triplets in an integer array where the sum of the three numbers is zero. While the concept may seem simple, achieving an efficient solution can be tricky, especially when working with larger arrays. In this post, we’ll dive deep into...
Today, we’ll explore LeetCode Solution 11: Container with Most Water, a classic problem that highlights the importance of efficient problem-solving techniques. If you’re gearing up for coding interviews or sharpening your algorithm skills, this problem is a great opportunity to practice optimizing solutions using the two-pointer technique. Problem Overview: Container with Most Water The task in...
Problem: 1 two sum Leetcode #1 solution – 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. Examples: Input: nums = [2...
Hi, I’m Peter, a professional developer with over 25 years of experience. My journey with coding started when I was just a kid, exploring the world of programming and building my first projects out of pure curiosity and passion. Since then, I’ve turned this lifelong passion into a rewarding career, working on a wide range of projects, from small scripts to complex applications.
Now, I’m here to help others get started with coding through this blog. I know that learning to code can feel overwhelming at first, but I believe that with the right guidance, anyone can develop the skills they need to become a proficient programmer. My goal is to simplify the learning process and provide step-by-step resources that make coding accessible, fun, and practical for everyone.
Whether you’re just starting out or looking to sharpen your skills, I hope this blog serves as a valuable resource on your coding journey. Let’s dive into Python together!
