- Python only* Use recursive function*. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters here is the specification for concentricCircles function: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. When viewed as nested rings, all rings should have the same thickness. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the outermost circle, and then every other circle in to the center alternates between that color and the other color. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order. Hint: Each function call frame only needs to draw a single circle. Note that you must use the turtleBeads drawDot function to draw each circle Do not use any kind of loop Within the definition of…Task using C language One common way of verifying if the data integrity of a file was preserved during a copy or transmission is to verify if the checksum matches. The checksum is a small piece of data computed from the original data. Your task is to compute a recursive function that maps an integer into a single digit to be used as checksum. Given an input integer in the range from 0 to 1012, the checksum is the sum of the digits of the input number. While the resulting sum has multiple digits, the checksum will be the sum of its digits instead. For instance: if the input is 34, the checksum is 7 (3+4); if the input is 99, the sum of its digits is 18 (9+9), so the checksum is 9 (1+8); if the input is 99999999999, the sum of its digits is 99 (9+9+9+9+9+9+9+9+9+9+9), whose sum of digits is 18 (9+9), so the checksum is 9 (1+8). Requirements Follow the format of the examples below. Make sure your variables and parameters have the correct data types. You must implement a recursive…Python program (recursive function) A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result. Write a python recursive functionprod that takes x as an argument, and returns the result where, result=1*1/2*1/3*….*1/n Include a screenshot that shows a python program that uses the above function and prints the rounded result to three decimal placesafter prompting the user to enter a number, x. Use x=3. N.B: The code should be included please.

Write a Cover Page function to print the HW details passing the needed parameters and has no return. b. Write a function that gets student grades and ID (maximum number of students is 20) then the function has a switch statement to enable the user to choose one of the following operation: i. Call MaxMin function to find and print the maximum and minimum grades as well as their ID ii. Call function Average to return the average grade of the class. iii. Call mark function to print students ID, their grades, and marks (as in the below table) iv. Call Sort function to sort the student ascending or descending based on their grades. The program will repeat the operation tile the user wish to terminate the program. Note: Student's grades are between 0 and 100 (use data validation technique). • You will get zero if you don't use comments and print HW details (your name, course name, course…Midterm Practice Problems 1. Use recursion to write a function count_ones that returns how many Is there are in a number n when represented in decimal (base 10). For example, 1231 has two 1s. You can assume that n is nonnegative and at most 9 digits long. Do not use global (or static) variables. In main perform at least three tests of count_ones and use assert to check that the returned value is correct. Your function should have the following prototype: // count_ones (n) returns the number of is in the decimal representation of n // requires: 0 <= n < 10^9 int count_ones (int n);The sum of the elements in a tuple can be recursively calculated as follows: The sum of the elements in a tuple of size 0 is 0 Otherwise, the sum is the value of the first element added to the sum of the rest of the elements Write a function named sum that accepts a tuple as an argument and returns the sum of the elements in the tuple.

Almost every enterprise application uses various types of data structures in one or the other way. There are various data structure techniques that can be used for storing data systematically by applying good algorithms. Design an algorithm that takes two arrays, and returns true if the arrays are disjoint, i.e. have no elements in common. Use standard data structures and algorithm in your solution without having to explain how they are implemented. Write down your algorithm as pseudocode. You don't need to write Java code but be precise so that a competent programmer should be able to take your description and easily implement it. Your algorithm should take Qn log m) time, where n is the size of the larger array and m is the size of the smaller array. Since n2 m, this is the same as Q(n log m + m log m). i. ii. Describe why it is a bad idea to implement a linked list version a queue which…
- C codeblocks Only write a function that receives an array, its size and a value to search for (define your function in the same way as the given function prototype). The function should return the index of the searched element in the array. If the element is not found, it should return -1. If the array has more than one element of that same value, it should return the value -2. The array is not necessarily sorted and should not be sorted in the function. #include <stdio.h>#include <stdlib.h>int searchIt(int arr[], int size, int value);int main() {int a[]={1,2,3,4,5};printf("%d", searchIt(a,5,3));return 0;}//Your answer starts here. For example: Test Result int a[]={1,2,3,4,5}; printf("%d", searchIt(a,5,3)); 2 int b[]={3,2,5,7,10,2,4}; printf("%d", searchIt(b,7,2)); -2 int c[]={-1,0,234,43,2,1,4,5}; printf("%d", searchIt(c,8,99)); -1(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.Problem: Recursive Power Method Design a python function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output. Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00
