Lesson Promise
By the end of this lesson, you will know how to avoid memory leaks using RAII and smart pointers, and how to use STL containers and algorithms effectively — choosing the right container and algorithm for each job.
Narration Draft
"The single most important rule in C++ is: never call new or delete manually. Instead, use RAII — Resource Acquisition Is Initialization — where an object's destructor automatically cleans up resources when it goes out of scope. Smart pointers like unique_ptr and shared_ptr implement this pattern for heap-allocated memory."

- Scene 3 — Container complexity table (vector vs map vs unordered_map)
- Scene 4 — Algorithm walkthrough: sort → binary_search → accumulate
