3. دیا i. Write a Python program that enables a user to enter a positive integer (>1) and display all integers from that down to 1 by using a recursive function. (Example: For a user input 5, the output should be 5 4 3 2 1). Input validation is required. ii. If x and y are two variables, write a Lambda function to evaluate the expression: f(x, y) = x²y + y²x for a given pair of values of x and y. (Example: f(1,2) = 2 + 4 = 6)

(Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.
In this lab, we will practice: Implementing recursive function printing in a recursive function (before and after the recursion function call) working on setting the base and general cases for the recursion function Instructions Write a recursive function called print_num_pattern() to output the following number pattern. Given two positive integers as input (Ex: 12 3), subtract the second integer (3) from the first one (12) and print the result continually until 0 or a negative value is reached. Then continually print the result of the addition of the second integer to the last value you reached from the subtraction (zero or negative) until the first integer is reached again. Note: For this lab, do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12 Hint You do not need to actually do addition. You can write statements i.e. printing statements after the recursion function call.
Write a python program that contains a function called reveal_recursive() that takes a word (string) and the length of the word (int) as input and has the following functionality:1. prints the word where all characters are replaced by underscores2. continue to print the word revealing one character at a time. i.e., the second line printed should print the first character followed by “_”’s representing the rest of the word. (see example below)3. the function should end after printing the entire word once.4. This function should be recursive Example: #the word is kangaroo________k_______ka______kan_____kang____kanga___kangar__kangaro_kangaroo
Write a program called p3.py that contains a function called reveal_recursive() that takes a word (string) and the length of the word (int) as input and has the following functionality: 1. prints the word where all characters are replaced by underscores 2. continue to print the word revealing one character at a time. i.e., the second line printed should print the first character followed by “_”’s representing the rest of the word. (see example below) 3. the function should end after printing the entire word once. 4. This function should be recursive Example: #the word is kangaroo ________ k_______ ka______ kan_____ kang____ kanga___ kangar__ kangaro_ kangaroo
In C++ Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is: 123 the output is: 12 9 6 3 0 3 6 9 12 #include <iostream> using namespace std; // TODO: Write recursive PrintNumPattern() function int main(int argc, char* argv[]) { int num1; int num2; cin >> num1; cin >> num2; PrintNumPattern(num1, num2); return 0;}
Can you help me with this program?In C++Write a program that finds all the ways in which the mouse can move to the cheese, and if any, display it with ‘*’.An example diagram of the task is shown in the figure: Operating instructions: Compose a recursive function path (int i, int j), receiving as parameters the coordinates of the current position of the mouse (initially 0.0, and then run with parameters (i-1, j), (i + 1, j), (i, j-1) or (i, j + 1)).
In C++ Consider the following recursive function (Chapter 17, #9, modified) void recFun(int x) { if (x > 10) { recFun(x / 10); cout<< x % 10; } else cout<< x; } How can the code be modified so that the sum of all digits is printed?
Consider the following recursive function: def rec1(aList,first,last): if first==last: return aList[first] else: return aList[last]*rec1(aList,first,last-1) Show the output of the following call (show your work and all recursive calls): print(rec1([1,2,3,4,5,6,7],3,5))? describe the task of the rec1 function.
Write a C++ function using recursion that returns the Greatest Common Divisor of two integers. The greatest common divisor (gcd) of two integers, which are not zero, is the largest positive inteteger that divides each of the integers. The code should follow the exact function declaration: int GCD(int number1, int number2);
Write in C++ a polymorphic and recursive function, print(x, n, w),which can print an object, x, the given number of times, n, separated by the user’s choice of white space character, w.Both n and w must be “default arguments”. The default value of “n” must be 1 and the default value of “w” must be the space character.(1) (2) (3)NB: If any part of your solution to a question has been extracted from a book, past tests or exams, then full disclosure must be given with complete references to the source. Non-disclosures will carry heavy penalties.
Consider the following recursive function: void recurse(int num) { if (num == 0) cout << “ Zero” << endl; else { cout << " " << num << " " << endl; recurse(num + 1) } } Is recurse (-2) a valid call? If a valid call, what is the output of the entire function execution? If not a valid call, explain why it is not a valid call.
An arithmetic sequence is a sequence of values where successive values have a common difference. For example, 2,5,8,11,... is an arithmetic sequence starting at 2 with a common difference of 3. We call the starting point s and the difference d. Fill in the missing lines below to write a recursive Python function called arithmetic that takes values for s, d, and n, and returns the nth term of the arithmetic sequence. For example, given the main function: def main(): for i in range(1,6): print(arithmetic(2,3,i)) the output will be: 2 5 8 11 14 Note: No marks will be given for a non-recursive solution. Code with missing lines: # Line 1 # Line 2 # Line 3 # Line 4 # Line 5 Matching each line of code below to its proper line number (Line 1 to Line 5), indicated in the partial code above, to solve the problem. Some lines of code will not be used at all; for these you would select option 6 (i.e., Not Used) from the list of options - do not leave these blank. Question 8 options:…
