Recursion Computer Science Quiz

What is recursion in computer science?

• A programming technique where a function calls a built-in library function to solve a problem.

• A programming technique where a function calls another function to solve a problem.

• A programming technique where a function calls itself to solve a problem.

• A programming technique where a function is called by multiple other functions to solve a problem.

Explain the concept of base case in recursion.

• The base case increases the number of recursive calls.

• The base case only works for iterative functions.

• The base case is optional in recursion.

• The base case stops the recursive calls and provides the solution directly.

How does recursion work in computer programming?

• Recursion is a process in which a function calls another function

• Recursion in computer programming is a process in which a function calls itself as a subroutine.

• Recursion is a process in which a function calls a built-in library function

• Recursion is a process in which a function calls a function from a different programming language

Why is recursion considered an important concept in computer science?

• It allows for elegant and efficient solutions to problems

• It consumes a lot of memory and slows down the program

• Recursion is not important in computer science

• It makes the code more complicated and harder to understand

Give an example of a recursive function in computer programming.

• sum = 0; for i in range(1, n+1): sum += i

• print('Hello, World!')

• def recursive_function(x): return x + 1

• factorial(n) = n * factorial(n-1)

What is the role of inductive reasoning in recursion?

• Making decisions based on intuition

• Using deductive reasoning to solve problems

• Forming a general rule or pattern based on specific cases.

• Ignoring specific cases and focusing on general rules

Give an example of using inductive reasoning in a recursive function.

• The Pythagorean theorem in mathematics

• The law of gravity in physics

• The factorial function in mathematics is a classic example of using inductive reasoning in a recursive function.

• The Fibonacci sequence in computer programming
