Description

The Calculator engine allocates and frees its own memory which leads to issues such as double-frees that are hard to investigate. We should clean this code and switch to modern constructs such as smart_ptrs to eliminate these issues.

Contributor guide

Research direction
Identify all raw pointer allocations in the Calculator engine and replace them with appropriate smart pointers (unique ptr, shared ptr, etc.). Ensure no memory leaks or double frees remain.
