I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Can you answer this question?

Sure. Recursion is a programming technique where a function calls itself. This can be used to solve problems that would be difficult or impossible to solve with a loop.

Here is an example of a recursive algorithm that prints the Fibonacci sequence:

Python

def fib(n):
    if n == 0 or n == 1:
        return n
    else:
        return fib(n - 1) + fib(n - 2)

The fib() function works by breaking down the problem of finding the nth Fibonacci number into two smaller problems: finding the (n - 1)th Fibonacci number and finding the (n - 2)th Fibonacci number. The fib() function then solves the smaller problems and then adds the two solutions together to get the solution to the original problem.

Here is an example of how the fib() function would be used to print the first 10 Fibonacci numbers:

Python

for i in range(10):
    print(fib(i))

This code would print the following output:
