Q10. rolling hash dsa problem
Rolling hash is a hashing technique used in data structures and algorithms to efficiently compare substrings of text.
Rolling hash is used in algorithms like Rabin-Karp string matching algorithm.
It involves updating the hash value of a substring by removing the contribution of the first character and adding the contribution of the next character.
It is useful for comparing substrings in constant time complexity.
Q11. Multi Threading in Java
Multi threading in Java allows multiple threads to execute concurrently, improving performance and responsiveness.
Multi threading is achieved in Java by extending the Thread class or implementing the Runnable interface.
Threads share the same memory space, allowing them to communicate and synchronize using methods like wait(), notify(), and notifyAll().
Concurrency issues like race conditions and deadlocks can occur in multi-threaded applications and must be carefully managed.

Q12. Synchronization in Java
Synchronization in Java ensures that only one thread can access a shared resource at a time.
Synchronization is achieved using the synchronized keyword in Java.
It can be applied to methods or blocks of code.
Example: synchronized void myMethod() { // code }
