Do you ever wish that you could make your Jeroo turn around 180 degrees?
Example 2 of a Custom Method to “Go Around a net”
You can download the files for the animation below here
Objective: Three Jeroos (you give them names) are practicing for the Santong Relays. Figure 5 shows the course at the start of the race. The first Jeroo begins at (4,9) facing EAST. It must pick the flower and give it to the second Jeroo who begins at (7,13) facing NORTH. The second gives the flower to the third Jeroo who begins at (4,15) facing WEST. The third Jeroo must plant the flower at (3,16), run to (3,21) and stop
I. Copy and paste this code below in the Jeroo “IDE”. Run the code several times unti you understand what is going on, then try experimenting with the code, changing it around until you are comfortable with the basic methods of a Jeroo.
Objective: Have a Jeroo spell out the lettter “Z ” in the same fashion as Part I

The assignment is to pick all the flowers for the map below.
You can use 2 loops for this, but you get extra credit for doing it in a single loop.
Scroll down to see a step by step visual of how 1 student did this in a single loop.
Assignment: Do any 5 of the required assignments. To get an A you must do “Spiral Inwards” assignment (see second from bottom)
You can also, skip everything and try the bottom map which is extra credit (and very, very hard). If you do that, you do not need to solve any other maps. Note: this is a very, very hard map, and I don’t recommend most people trying to do the extra credit until they’ve done the required ones.

Brett’s Maze 2
George’s Map : Start at ( 10,0) , facing SOUTH, Use 1 loop and pick the flower.
To get an A you must do the following assignment.
Objective: To use while loops to get the Jeroo to pass through each maze and get the flower. It is possible to write a solution to both of these mazes using a single while loop–albeit this loop will have several( about 5 or 6) if tests! It is important for this problem that you do NOT simply hand code this. To get an A on both of these assignments you must use 1 single while loop per maze.

2) Mazes 2 (start in top left, 1 loop to pick flower)
3) island-3-D (start in the top left, and get to the bottom right)
4) ZigZag : Use 1 while loop (not infinite), follow the flowers, picking them up and use those flowers traverse over the nets
5) Spell Z (Blank Map)
Last and most definitely not least:
island3-C ** A+ assignment.
This is the deceptively hard and should be done last and only if you want that A+
Done all of the maps? Start on the next set here
Start you jeroo in the bottom picture and have it climb to the flower. Use 1 and only 1 while loop.
Objective: A Jeroo starts at the southwest corner of the island, location (23,0), facing East with no flowers. There is a flower somewhere east of the Jeroo. There are zero or more hurdles, represented by nets, between the Jeroo and the flower. Each hurdle is a rectangular arrangement of nets with its base along the Southern Sea. The height and width of each hurdle is unknown. The number of hurdles and the spacing between the hurdles is unknown. There is at least one row of empty cells along the top and sides of each hurdle. There are no water features and no other Jeroos on the island. The only nets are those that define the hurdles. The goal of this program is to have the Jeroo jump all of the nets, pick the flower, and stop. A representative island is shown in figure 1.

One Saturday morning, two friends, Bugs and Daffy, decide to meet and plant flowers to beautify Santong island. Daffy starts in the Northwest corner facing East with 90 flowers in his pouch. Bugs starts in the Northeast corner facing West with 90 flowers in his pouch. Bugs and Daffy begin hopping toward one another. As they hop, each plants exactly one flower at every location it enters, including its starting location. They meet, facing each other, roughly in the middle of row 0. After a handshake and a little small talk, Bugs and Daffy both turn toward the south and continue planting flowers all the way to the southern edge of the island. When both reach the South Sea, the say goodbye and part. Daffy turns west and plants flowers all the way to the Western Ocean. Bugs turns east and plants flowers all the way to the Eastern Ocean. This is where our story ends. Your task is to write a Jeroo program that will illustrate this story.
One possible solution to this project is represented in the picture below

Acknowledgement This problem is adapted from one that was created originally by Erica Eddy of The University of Wisconsin – Parkside.
Your jeroo is exploring the outer perimeter of the lake. It starts next to a flower and travels the entire way around the lake. Have your jeroo stop immediately before the flower (using a loop) and then, after the loop is over, your jeroo should pick the flower.
