# 1. Reeborg Review¶

To confirm that you understand the major concepts we learned from our Reeborg unit, try the following without looking back at any previous code!

## 1.1. Question 1 - Apple Pie¶

Reeborg must walk around the outside of the world, collecting all the apples so that it can make apple pie when it gets home.

Try to make your code as short as possible using for/repeat loops.

Beware! The apples keep changing locations each time you reload this world.

Open the Apple Pie world and create a solution to this problem!

## 1.2. Question 2 - Go To Origin¶

Define a new function called `go_to_origin` that sends Reeborg to the bottom left corner of the screen (south-west corner), regardless of its initial location or the direction it is initially facing. Assume that there are no wall sections present.

Hint: Use the south and west boundary walls as guides.

## 1.3. Question 3 - Hurdle Jumping¶

Reeborg is jumping hurdles again. This time, the hurdles can be of any height, and of any width. Reeborg needs to keep jumping over them until it gets to the flag.

## 1.4. Question 4 - Planting Time¶

Reeborg has planted carrot seeds in the garden, but the carrots are growing unevenly. At some places, no carrots have grown; at others, many carrots are growing.

Have Reeborg remove the excess carrots and plant new ones where there is none so that there is only one carrot at each location. Reeborg already carries enough carrots (seeds) to replant the entire garden if needed.

You might find it convenient to define a function named `fix_one_row`, then call the function 6 times.
