Introducing TraceLit — visual algorithm tracer for LeetCode practice
Hey everyone! I just launched TraceLit on Product Hunt. TraceLit lets you paste your Python code, enter a test case, and step through execution line by line — while watching linked lists and binary trees transform as interactive node graphs. Built it because I kept losing track of pointers when dry-running on paper. Now I can see exactly where prev, curr, head point at every step. Key features:...

Hey everyone! 👋 Visualizing pointer logic in your head is hard. That’s why I created TraceLit—a visual execution tool designed to help you ace those tricky data structure interviews. What makes it different? Visual Execution: Watch nodes and pointers move in real-time as you step through your Python code. Interactive Graphs: No more static diagrams; see exactly where your head, curr, and null...
