Partitioning
Partitioning, in its simplest form, is about organizing sequences based on specific criteria, ensuring that all elements for which the requirements hold true precede those for which it does not. It is about segregating data efficiently, optimizing its organization for rapid access, and enhancing computational efficiency.
The C++ STL offers a rich set of algorithms for partitioning tasks. While one might be tempted to use simple loops and conditionals to achieve such tasks, these STL functions are optimized, tested, and designed to offer the best performance. These algorithms are implemented by experts who have a deep understanding of the underlying system, handle the edge cases, and typically take advantage of compiler optimizations and even (potentially) parallelization.
std::partition and its power
One of the most foundational functions in this category is std::partition. This function reorganizes elements in a range based on a predicate. It ensures that all...
