Write a multi-thread using C/Java/Python code and then learn how to create and terminate multiple threads.

In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to execute multiple processes or threads concurrently, supported by the operating system. This approach differs from multiprocessing. In a multithreaded application, the processes and threads share the resources of a single or multiple core, which include the computing units, the CPU caches, registers, etc.

Where multiprocessing systems include multiple complete processing units in one or more cores, multithreading aims to increase utilization of a single core by using thread-level parallelism, as well as instruction-level parallelism. As the two techniques are complementary, they are sometimes combined in systems with multiple multithreading CPUs and with CPUs with multiple multithreading cores.

1. Create at least 2 threads.

2. Each thread must do some task. Thread-1 must perform addition from 1 to 1000. And Thread-2 must perform addition from 3000 to 4000. Finally, print the results.
