About

Data Structure Display

Explore and learn data structures through dynamic debugging and visual observation of changes. This app covers linear structures, trees, graphs, and recursive algorithms like the Tower of Hanoi, offering interactive learning experiences.

Highlights
  • Dynamic data structure debugging
  • Visual observation of data structure changes
  • Learn linear structures (arrays, lists, queues, stacks)
  • Explore tree structures (binary, AVL, red-black, heap)
  • Understand graph structures and algorithms
  • Debug recursive algorithms like Tower of Hanoi
Features
Read full description

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.

Verdict

The call

The clearest difference is rating: Data Structure Display at 4.5 against Data Structures's 3.1. Data Structure Display also leads on ratings volume (676 vs 7). Data Structures's advantage is in-app purchases (none vs 1) and review sentiment (86% vs 62%). On price, ads and device support there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase. Data Structures asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Data Structure Display holds the better App Store score, 4.5 against 3.1. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 86% of Data Structures's written reviews are positive against 62% of Data Structure Display's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Data Structures ships an update every 3 months, Data Structure Display every 5 months. The most recent releases landed on September 23, 2026 and October 3, 2026 respectively.
