# Banana Cake
## Instructions

1. Assume an action set of {add \<ingredient>, stir, bake, cool}. Draw a flowchart, using the paradigm discussed in class, to show the process of baking a banana cake. Use Google to find a typical list of ingredients.
2. Represent the flowchart from problem 1 as pseudocode.

## Flowchart
```d2
vars: {
	d2-config: {
		dark-theme-id: 200
	}
}
grid-columns: 3

begin: {
	shape: oval
	# near: top-left
}

begin -> add 3c flour\
-> add 1 1/2 tsp baking soda\
-> add 1/2 tsp cinnamon\
-> add 1/2 tsp salt\
-> stir\
-> add 3 mashed bananas\
-> add 1 tsp lemon juice\
-> stir again\
-> add 3 eggs\
-> add 2tsp vanilla extract\
-> stir a final time\
-> bake @ 350f for 50 min\
-> let cool for 1 hour\
-> end
end: {
	shape: oval
	# near: bottom-right
}
```

# Walking
## Instructions
3. Assume an action set of {walk \<value> steps, turn to \<value> degrees}. Draw a flowchart showing a shady path and a sunny path to get from the west doors of the Engineering Building to the south-east doors of the TSC. Pick a meaningful “if” condition to select one of the two paths. Use real-world data in your design.

4. Represent the flowchart from problem 3 as pseudocode.

%% 
Assuming a step distance of 2.5 feet.

Shady path:
1. Turn to 270 degrees
2. Walk 112 steps
3. Turn to 225 degrees
4. Walk 124 steps
5. Turn to 270 degrees
6. Walk 361 steps
7. Turn to 0 degrees
8. Walk 176 steps
9. Turn to 270 degrees
10. Walk 62 steps


Sunny path:
1. Turn to 270 degrees
2. Walk 73 steps
3. Turn to 0 degrees
4. Walk 94 steps
5. Turn to 275 degrees
6. Walk 467 steps
7. Turn to 180 degrees
8. Walk 86 steps
9. Turn to 270 degrees
10. Walk 80 steps
