Solved LeetCode 5: Longest Palindromic Substring with Two Pointers and DP

Had some fun by bringing art to life with Python! I created this hypnotic pattern using the turtle library for the graphics and the colorsys library to dynamically generate that smooth color transition. It's a simple script, but it’s a great exercise in using loops and hsv_to_rgb conversion to create something visually complex. It's always so satisfying to watch the program draw it line by line. I've attached a video of the code and output. #Python #CreativeCoding #TurtleGraphics #CodeArt #Programming #Developer #Tech #Visualization

Day 64: Distinct Subsequences (Dynamic Programming) I'm focused on challenging algorithms on Day 64 of 100DaysOfCode with "Distinct Subsequences." The goal is to count how many unique ways a shorter string (t) can be formed by deleting characters from a longer string (s). My solution uses Dynamic Programming (DP), which is essential for this combinatorial counting problem. The DP table tracks the number of ways to form prefixes of t using prefixes of s. The key recurrence relation is: we either dont use the current character of s or, if they match, we add the ways we could form the previous prefix of t. This methodical approach correctly counts every distinct subsequence, running in O(m * n) time. #Python #DSA #Algorithms #DynamicProgramming #DP #100DaysOfCode #ProblemSolving

Day 44 of #100DaysOfCode, solving "Longest Common Subsequence (LCS)." This problem requires finding the longest sequence common to two strings, even if characters are separated. My solution uses Dynamic Programming (DP), which breaks the problem into smaller, overlapping subproblems. DP Table: I built a table (optimized to use only the previous row) to store the length of the LCS found so far. The Rule: If characters match, the LCS length increases by 1 (coming from the diagonal cell). If they don't match, the length is the maximum of the two adjacent cells. This systematic approach guarantees the optimal result, solving the problem in O(m * n) time complexity. #Python #DSA #Algorithms #DynamicProgramming #LCS #100DaysOfCode #ProblemSolving

Day 13: #100DaysOfCodingChallenge 🚀 Focusing today on in-place array transformation patterns in Python, specifically replacing each element with the greatest value among those to its right. 📌 Today's Progress: 1️⃣ Replace Elements with Greatest Element on Right Side (LeetCode 1299) 👉Problem: Modify the array so each element is replaced by the greatest element to its right (final element set to -1). 👉Approach: Scanned the array from right to left, tracking the current maximum 'max_right' and updating each value in-place. Achieves O(n) time and O(1) space with a clean backwards pass. Practising these in-place update patterns helps build critical skills needed for real-world coding and interview scenarios.
