What is a stub? Group of answer choices A stub is an inline function with a single line that simply sends a "Hello" message to others, indicating that it has been activated. A stub is a function that has an empty body. It will be developed later. A stub is an inline function with a single line that simply increases the pass in value by one. A stub is a function with a single line that simply prints the name of the function, indicating that it has been activated. A stub is a short function that will generate an error message.

1. Square Flower You can have the turtle draw an interesting flower like sha pe by drawing n squares. Each n-square flower is drawn after turning the turtle by some number of degrees between each square. (see Figure 1 for an example) (a) Typel: A 5-square red flower. (b) A 15-square blue flower. Figure 1: Two types of n-square flowers Using the following implementation of draw square() function write a function na med draw flower() that takes a turtle, the number n of squares to draw, the side length and a color as parameters and draws an n-square flower by repeating the function draw square() n times. Test your code by drawing a yellow 21-square flower with side length of 200. def drav aqu ar e (aTurtle, sidelength): f or i in range (4) : aTurtle.forvard (side Length) aTurtle. 1eft (90)
