Why do multithreaded programs use separation of read and write operations when working with RWMutex?

In a multithreaded program, RWMutex (Read-Write Mutex) is used to optimize access to shared data. Separating read and write operations allows multiple threads to read data simultaneously without blocking each other, which increases performance during frequent read operations.

At the same time, writing blocks access for both readers and other writers to prevent race conditions and ensure data integrity. Thus, RWMutex allows efficient resource utilization, minimizing lock times during reading and ensuring safety during writing.
