Challenge $4($Extra Credit$)$

Overview

For this programming challenge you will use Turtle to draw trees and people $($stick figures$).$

Instructions:

Below are the four functions that you need to have to complete this challenge:

Tree$($t$,$ color$)$: the function should accept a turtle object and a color $($string$)$ and draw a tree in that color. The core of the tree is an equilateral triangle $($all sides are equal$).$

Human$($t$,$ color$)$: the function should accept a turtle object and a color $($string$)$ and draw a human $($stick figure$)$ in that color. The function should use the circle function to draw the head of the human.

Circle$($t$)$: the function should accept a turtle object and draw a circle.

Main$()$: the function should prompt the user for the number of tree$-$human pairs he'd like to draw and their colors $($hint: can store colors in lists$).$ The program should then use the Tree and Human functions to draw the number of tree$-$human pairs. For each pair, a tree should be drawn first followed by a human. The ground should be drawn in green connecting all the trees and humans.
