1. Recursive Multiplication
Write a recursive function that accepts two arguments into the parameters x and y. The
function should return the value of x times y. Remember, multiplication can be performed
as repeated addition as follows:
7* 4 = 4 + 4 + 4 +4 + 4 + 4 + 4
Recursive Power MethodWrite a method called powCal that uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponent and the second argument is the number to be raised (example” powCal(10,2) means 210). Assume that the exponent is a nonnegative integer. Demonstrate the method in a program called Recursive
(This means that you need to write a program that has at least two methods: main and powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCal method work).

The numbers at the edge of the triangle are all 1, and each number inside the
triangle is the sum of the two numbers above it. Write a procedure that computes
elements of Pascal's triangle by means of a recursive process.

A string is a palindrome if it reads the same forwards or backwards. Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position a and continuing to (but not including) the character at position b.

- Python question Application: Python Fragment Formulation (Q1 – Q4) In this group of questions you are asked to produce short pieces of Python code. When you are asked to "write a Python expression" to complete a task, you can either give the expression in one line or break down the task into several lines. The last expression you write must represent the required task. Question 1 (Reduce parentheses) Give an equivalent version of this expression by removing as many redundant parentheses as possible, without expanding the brackets or simplifying. (x**(2**y))+(y*((z+x)**3)) Question 2 (Translate arithmetic concept into Python) You are given a list of numbers, named numbers, containing 3 integers. Write a python expression (one line) that evaluates to True if and only if the product of any two numbers in the given list is greater than the sum of all three numbers. Note: the product of two numbers, x and y is x*y. Question 3 (List/table access) You are given a table,…arrow_forwardMagic Number coding question---1.

Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the function will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum. solve using Pythonarrow_forward
