Basic JavaScript, React state, arrays, recursion, and SVG rendering.
Data structures
Binary Search Tree Data Example
Add numbers, convert a sorted array into a balanced binary search tree, and search the tree while tracing the execution path.Current Array: [10, 20, 30, 40, 50]Sorted Array: [10, 20, 30, 40, 50]
Tutorial: Visualizing a Binary Search Tree in React
This demo starts with a static array. Each added value is deduplicated, sorted, and used to create a balanced binary search tree. Searching compares the target value against each node and moves left or right until the value is found or the path ends.
2. Generate the Tree
Pick the middle value as the root, recursively build the left half, and recursively build the right half.
3. Search
Compare the selected number with the current node, record the path, then recurse left or right based on the comparison.
