Data Structure Display vs Tany Space App

A novel data structure learning app, the most significant feature is that you can dynamically debug the data structure in this app, and visually observe the changes in the data structure during the operation. In this app you can learn the following data structures: 1. Linear structures, including arrays, linked lists, queues, stacks. Linear structures are the basis for other advanced data structures, as fine as advanced algorithms. 2. Tree structures, including binary tree, binary search tree, AVL tree, red-black tree, and heap. In this app, you can dynamically debug three traversals of the binary tree (including non-recursive traversal implementations), searching in the tree, balance adjustments in the AVL tree and red-black tree, and heap sorting. Give you the ability of handwritten red-black trees. 3. Graph structure, including the adjacency list storage representation of the graph structure, depth-first search and breadth-first search, finding the Euler path in the graph, topological sorting, maximum connected components, minimum spanning tree problem, and shortest single source Path problem. It also provides dynamic debugging of these classic graph algorithms. 4. The data structure introductory class will talk about the problem of the Tower of Hanoi. The algorithm that solves this problem is often recursive. This app provides dynamic debugging of the Tower of Hanoi problem, so you can no longer be confused about the recursive calls of the Tower of Hanoi.

Tany turns real orbital science into something a kid can actually build. TRACK THE REAL SKY See live satellites, the International Space Station, Starlink constellations, and space debris in a real 3D Earth — powered by real public tracking data (CelesTrak), using real orbital mechanics. Tap anything to see its altitude, speed, orbit, and story. BUILD YOUR OWN ROCKET Design a rocket piece by piece — nose cone, body, fins, engine — then build and name a satellite with a real mission (weather, communications, science, navigation, Earth observation). This isn't a toy simulation: your rocket joins a real launch queue. REAL LAUNCH DAYS Rockets don't launch instantly — they queue up for a scheduled Launch Day at a real spaceport (Kennedy Space Center, Baikonur, Guiana Space Centre, and more), just like actual missions batch payloads together. Once launched, track your own satellite in orbit alongside real ones, forever. MEET TANY Tany is a friendly AI space companion built specifically for space and science questions — strictly on-topic, kid-appropriate, and won't do a student's homework for them. Ask about anything happening in orbit, from a satellite's mission to real recent space news. BUILT FOR SCHOOLS See how many students and schools around the world have launched their own satellites. Nicknames and school names only — never a real name, precise location, or a public email address. Tany Pro (optional, one-time purchase) removes daily limits on chatting with Tany and unlocks unlimited rocket launches — your first launch and 10 daily questions are always free.
