…es and algorithms

- Introduced a detailed overview of Binary Trees, including properties, types, and mathematical concepts like Catalan numbers.
- Added common algorithms for generating binary trees from traversal data and counting nodes, leaf nodes, height, and levels.
- Created separate sections for Full vs Complete Binary Trees, Strict Binary Trees, and N-ary Trees, highlighting their definitions, properties, and differences.
- Implemented tree representation methods in memory, covering both array and linked representations.
- Documented various tree traversal techniques, including Depth-First and Breadth-First traversals, with Python code examples and complexity analysis.
