👉 Parecy is a concept in computer science that refers to the property of a data structure or algorithm where all possible paths from an initial node to any other node are traversed in the same order, without any cycle. This property helps in solving problems efficiently and ensuring the integrity of data structures. In the context of algorithms, parecy ensures that the algorithm behaves as expected on both parallel and serial execution scenarios, which is crucial for robustness and scalability of applications. It also helps in reducing memory
