🎯 About

🎓 This project was completed as part of the educational module at the Higher IT School of TSU (Tomsk State University) on mobile development

📱 It was necessary to implement an algorithm interpreter in the form of a mobile application

✅ App Features:

• Change the sequence of blocks on the workspace by drag and drop
• Wiggle mode
• 17 blocks are available for writing your algorithm
• Remove any block or all
• Block data is stored regardless of the current screen
• User can save his algorithm
• The preview of the saved algorithm uses its image
• Preview on the workspace
• Table of blocks with sections of block types

✅ Interpreter:

We utilized an Abstract Syntax Tree (AST) to construct and execute commands.

The features include:

• Variable declaration and initialization
• Support for complex arithmetic expressions with parentheses
• If, else-if, else statements
• Comparison operations and logical operators
• While and for loops
• Block scoping with begin/end
• Dynamic array declaration and manipulation (append, remove, pop)
• Element access by index
• Continue and break statements
• Logical operators with boolean values
• Function implementation with variable scope
• Support for multiple data types (int, double, bool, string)
• Type conversion and automatic type inference
• Type checking for variables
• String concatenation for any string types
