The LeetCode 14 solution to the “Longest Common Prefix” problem challenges you to find the longest prefix shared by a group of strings. A prefix is a substring that appears at the start of a string. The task is to determine the longest prefix that is common across all strings in the array. If no common prefix exists, the function should return an empty string. This problem is...
When tackling coding challenges like LeetCode’s “Roman to Integer” problem (LeetCode 13), it’s essential to not only solve the problem but also understand the process behind it. In this post, we will walk through a complete LeetCode 13 solution with clear explanations. The goal is to convert a Roman numeral into an integer, using Python. Roman Numerals: What You Need to Know Roman...
LeetCode 12 Solution presents one of the most interesting challenges by requiring the conversion of integers into Roman numerals. While the Roman numeral system may seem ancient, it offers a fascinating way to sharpen your algorithmic skills through its unique rules for converting numbers. The problem asks us to take an integer and convert it into its corresponding Roman numeral using a...
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...
If you’re looking to crack hard LeetCode problems, the “LeetCode 10 solution” is a fantastic start. It will help improve your understanding of dynamic programming and string manipulation. This problem involves implementing a regular expression matching algorithm, where you’re given two strings: the input text and a pattern. The key difficulty here lies in the fact that the pattern can...
In this blog post, we’ll dive into the LeetCode 9 solution for the Palindrome Number problem. If you’re preparing for coding interviews or looking to level up your problem-solving skills, this problem is a fantastic way to practice working with numbers in Python without resorting to string manipulation. Let’s explore the logic and code to solve this popular problem efficiently. Problem...
Looking for a comprehensive explanation and LeetCode 8 solution? You’re in the right place! The “String to Integer (atoi)” problem on LeetCode, also known as LeetCode problem #8, is a common interview question that tests your ability to convert a string into a 32-bit signed integer while handling various edge cases such as whitespace, signs, and overflow. In this blog...
The LeetCode 7 solution seems simple, but when you’re dealing with constraints like 32-bit signed integers, things get tricky. LeetCode’s Reverse Integer problem asks us to reverse the digits of an integer, but we also need to watch out for overflow. In this post, I’ll walk you through two solutions: one using string manipulation (with a catch) and a better solution using...
In the LeetCode 6 – “Zigzag Conversion” problem, we are given a string s and an integer numRows. The string should be written in a zigzag pattern across numRows rows. After forming this zigzag pattern, the task is to read the characters row by row and return the resulting string. For example, with the input string "PAYPALISHIRING" and numRows = 3, the zigzag pattern looks like:...
LeetCode 5 Solution – The Longest Palindromic Substring: the problem asks us to find the longest substring within a given string s that reads the same forwards and backwards. A palindrome is a word or sequence of characters that is identical when reversed. For example, in the string "babad", both "bab" and "aba" are palindromic substrings, with a length of 3. Given a string s...
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!
