Drawing with Math vs LeetAICoder

Our “Drawing with Math (Vector and Pixel Art)” app combines two main components: * uniquely versatile image editors, * various methods of linear transformations of both user-entered and system images. Image editors are available in vector and pixelated forms. The editors offer such options as: * free drawing, * entry of all standard shapes, * entry of regular Cartesian, polar, or parametric function into image editor. List of several visually appealing functions is provided. The App stores 10 most recent user entries for each type. Vector images can be linearly transformed in a variety of user-defined ways: * 2x2 matrix, * eigenvalues and eigenvectors, * rotation by degree, * reflection across a given vector. Pixelated images can be compressed by segments to user-selected rank. Mathematical context for the above is provided, whenever possible. Explanation of image compression algorithms requires significant understanding of Linear Algebra, and is available in our “Matrix Solver Step by Step” app. Several bonus images with animations and editable greeting cards are also available. Suggestions and any other feedback are welcome! Write to us at graphmath@aol.com.

LeetAICoder is prompt-only practice for coding problems. You do not open an editor and hand-write submissions. You explain your intent in natural language, the on-device AI authors every line of the runnable solution, and the app executes and grades it locally against real tests. Inside the app: * First AI Program — Learn the workflow on a simple task: steer the model until tests pass. * Challenges — Same rules on curated LeetCode-style problems: language in, code from the model out. * Leaderboards — Total and per-problem standings; sign in to Game Center for optional global boards.
