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)
