e four functions: n iterative function that accepts a non-negative integer n and returns the nth Fibonacci number. recursive function that inputs a non-negative integer n and returns the nth Fibonacci number. n improved recursive function that employs dynamic programming to improve the efficiency. ne closed form of the Fibonacci sequence (be sure to reference the golden ratio)

PYTHON PLEASE Design a class named Triangle that extends the GeometricObject super class. The Triangle class contains: Three float data fields named side1, side2, and side3 to denote the three sides of the triangle. A constructor that creates a triangle with the specified side1, side2, and side3 with default values 1.0. The accessor methods for all three data fields. A method named getArea() that returns the area of this triangle. A method named getPerimeter() that returns the perimeter of this triangle. A method named __str__() that returns a string description for the triangle.   Formula to compute the area of a triangle, . Where    The __str__() method is implemented as follows:   return "Triangle: side1 = " + str(side1) + " side2 = " + str(side2) + “ side3 = " + str(side)   Draw the UML diagrams for the classes Triangle and GeometricObject. Implement the Triangle class. Write a test program that prompts the user to enter the three sides of the triangle, a color, and 1 or 0 to…

Coding in python Please!!I need help please help me in the easiest way to do this coding question. Please do not post it's answer from chegg just use your own skills to write code in easyiest way possible. I will really appriciate your help. Coding language PYTHON : The purpose of this assignment is to help you get comfortable creating and using simple classes and objects. In this assignment, we wish to model a 2-D video game character’s movements.  In particular, suppose we are creating a tiny game, where the character can occupy one of 25 squares, like so:     The first thing we need to keep track of is the character’s name, so we can differentiate this character from other characters or enemies.  The other thing we need to keep track of is the character’s position, i.e., which square they are in.  In order to do this, we’ll use an X-Y coordinate system with the origin in the top left corner (the 0,0 square in the picture).  So, in the picture, the character occupies square 3, 2;…
