Questions and Answers related to STL Development

In C++, what is STL? Why should one use this in coding challenges

“STL means “Standard Template Library”, which in turn means a set of type independent functions and classes that are part of the standard C++ language runtime. “Template” means that most types (including primitives, class / struct based types including user defined ones) would possibly be able to work with STL, however the type needs to behave like a good “value type”. A main part of STL is the containers and iterators which covers basic data structures including vector, linked list, hash and tree based maps…”

What is the difference between unordered_set and vector in C++?

“You can quickly access the elements in a vector by position (e.g., “give me the 27th element). Because an unordered set is, well, unordered, you can’t do the same there. You can quickly access the elements in an unordered set by key (e.g., give the the element that compares equal to X). Doing this in a vector is very slow. You can insert and remove items in an unordered set quickly. In a vector, you can insert/remove at the end of the vector quickly, but in the middle it gets expensive…”

What is the typical implementation of an unordered_map and map in the C++ STL?

“Yean, std::map implementation is based on LLRB trees. The tree implementation has the advantage that iteration of the key-value pairs contained in the map is done in key-order. A tree implementation has O(logn) cost for both insertion and retrieval. Deletion also has a logarithmic complexity. std::unordered_map is introduced in C++ 11 with a hash map implementation, as the name implied it loses the property of being ordered. The iteration of the key-value pairs is not in key-order, it has O(n) cost for both insertion and retrieval.”

What is the benefit of STL in C++?

“STL is the basic building block for everything else. You simply can’t program the C++ without knowledge of STL. That doesn’t mean you need to know every bit of it, but you should familiarise yourself with the concept of templates, and why are they so powerful. They basically allow your class to work the same with int and float and any other data type as long as you implement the proper logic in your template function. You have a lot of boilerplate code written for you. So that means that you don’t reinvent the wheel, but you basically take a wheel that someone else made…”
