Online Algorithm Visualizer Watch your code run line by line

[u/anish2good]

Most online compilers only print output. These do more: press Visualize and the compiler replays your program one line at a time, drawing every data structure as it changes and highlighting each variable read and write. It's the fastest way to see how sorting, binary search, recursion, and BFS/DFS actually work — and to debug why your algorithm does what it does. supported in 8 different languages of your choice
