Concept explainers
A function which calls itself is called as recursion.
Hence, the correct answer is option “C”.
Explanation of Solution
Recursion:
Recursion is a process where function is called again and again by itself for a specific number of times.
- There are two types of recursive functions. They are as follows:
- Direct recursion
- Indirect recursion
Direct recursion:
When a function calls the same function repeatedly until the condition becomes false, then it is called as direct recursion.
Indirect recursion:
When a function calls another function which in turn calls the same calling function, then it is called as indirect recursion.
Example:
Consider the following example; the function “Add()” can be called itself in the same function definition. Hence, it comes under direct recursion.
#Define the Add()function
def Add()
#Print the message
print('Example of recursive function!!')
#Call the Add() function recursively
Add()
Explanation for wrong options:
A recursive function cannot call the different function.
Hence, option “A” is wrong.
A recursive function cannot halt the program.
Hence, option “B” is wrong.
A recursive function can call more than once in a program.
Hence, option “D” is wrong.

- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forwardProblem Statement for Recursive Sum of Numbers Program Here is a simple recursive problem: Design a function that accepts a positive integer >= 1 and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 10 is passed as an argument, the function will return 55. Use recursion to calculate the sum. Write a second function which asks the user for the integer and displays the result of calling the function. Part 1. Understand the Problem To design a recursive function, you need to determine at least one base case (the base case returns a solution) and a general case (the general case calls the function again but passes a smaller version of the data as a parameter). To make this problem recursive think about it like this: If the integer is 1, the function will return 1. If the integer is 2, the function will return 1 + 2 = 3. If the integer is 3, the function will return 1 + 2 + 3 = 6. . . . For this problem, we will be sending in the "last"…arrow_forwardJAVA CODE PLEASE Recursive Functions Practice l by CodeChum Admin Create a recursive function named fun that prints the even numbers from 1 to 20 separated by a space in one line.

In the code editor, you are provided with a main() function that asks the user for two integer inputs: 1. The first integer is the base 2. The second integer is the result 2. Furthermore, you are provided with the getExponent() function. The details of this function are the following: 1. Return type - int 2. Name - getExponent 3. Parameters 1. int - base 2. int - result 4. Description - this recursive function returns the exponent 5.

- Write a recursive function called digit_count() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10. Ex: If the input is: 345 the function digit_count() returns and the program outputs: 3 # TODO: Write recursive digit_count() function here. if __name__ == '__main__': num = int(input()) digit = digit_count(num) print(digit)arrow_forwardplease help in this codearrow_forwardN.B: Use all the recursive functions in one C++ code 1.

- When all the statements are executed before calling the function, the calling comes at the end of code lines, this called: O a. Head recursion O b. Endless recursion Recursive call O d. Tail recursionarrow_forwardA recursive function typically has two components: one that provides a means for the recursion to terminate by testing for a(n)____________ case, and one that expresses the problem as a recursive call for a slightly simpler problem than the original call.arrow_forwardComputer science C prog Create a recursive function that finds if a number is palindrome or not(return true or false), A palindromic number is a number (such as 16461) that remains the same when its digits are reversed.
