v1.1.0

What’s New in v1.1.0 🚀

This release makes it easier to understand not only the final answer, but how the algorithm got there.

New Visualizations

• Largest Rectangle Area View — Follow the monotonic stack, active rectangle, and best area, including sentinel and final-flush implementations.
• Expression View — Step through calculator expressions with the current character, accumulated result, and sign context.
• Word Ladder View — Explore BFS levels, queue state, visited words, and active transformations.
• Heap View — Watch values move between MinHeap and MaxHeap in algorithms such as Median Finder.

Better Runtime Debugging

• Call Frame Inspector — Inspect active, suspended, and completed recursive calls with their arguments and local variables.
• Previous Variable Change — Jump directly to the previous step where a selected variable changed.
• Improved step-review guidance after execution completes.

More DSA-Friendly Inputs

• Added built-in MinHeap and MaxHeap implementations.
• Added support for ListNode[] inputs, including linked-list arrays and cycle aware structures.

Reliability Improvements

• Improved Trapping Rain Water and histogram detection.
• Preserved non-JSON values such as NaN, Infinity, BigInt, and cyclic structures across runtime snapshots.
• Improved recursive frame snapshots, class receiver tracking, visualization fallback behavior, and modal scrolling.

Thanks for using DSA View View! 👀👀

v1.0.0

DSA View View 👀👀

Turn algorithms into visual stories.

The very first release of DSA View View is here! 🎉

Write TypeScript algorithms, run them with structured inputs, and watch every step come to life from arrays and matrices to trees, linked lists, stacks, and pointers.

What’s Inside 🧠⚡

• Step through real TypeScript code in your browser
• Visualize arrays, matrices, trees, linked lists, stacks, and more
• Explore 39 built-in algorithm examples
• Follow execution frame by frame
• Share the exact code, input, view, and runtime step with a URL
• Meet ViewView, your tiny algorithm-monitoring friend 📺👀

Perfect for debugging solutions, learning data structures, explaining algorithms, or finally turning:

“I think I get it…”
into
“Ohhh, now I can see it!” ✨

Try It 🚀

👉 Open DSA View View

If algorithms are hard to picture, let’s make them visible. 👀👀
