# Instructions
2+
3+
Your task is to, given a diagram, determine which plants each child in the kindergarten class is responsible for.
4+
5+
There are 12 children in the class:
6+
7+
- Alice, Bob, Charlie, David, Eve, Fred, Ginny, Harriet, Ileana, Joseph, Kincaid, and Larry.
8+
9+
Four different types of seeds are planted:
10+
11+
| Plant | Diagram encoding |
12+
| ------ | ---------------- |
13+
| Grass | G |
14+
| Clover | C |
15+
| Radish | R |
16+
| Violet | V |
17+
18+
Each child gets four cups, two on each row:
19+
20+
```text
21+
[window][window][window]
22+
........................ # each dot represents a cup
23+
........................
24+
```
25+
26+
Their teacher assigns cups to the children alphabetically by their names, which means that Alice comes first and Larry comes last.
27+
28+
Here is an example diagram representing Alice's plants:
29+
30+
```text
31+
[window][window][window]
32+
VR......................
33+
RG......................
34+
```
35+
36+
In the first row, nearest the windows, she has a violet and a radish.
37+
In the second row she has a radish and some grass.
38+
39+
Your program will be given the plants from left-to-right starting with the row nearest the windows.
40+
From this, it should be able to determine which plants belong to each student.
41+
42+
For example, if it's told that the garden looks like so:
43+
44+
```text
45+
[window][window][window]
46+
VRCGVVRVCGGCCGVRGCVCGCGV
47+
VRCCCGCRRGVCGCRVVCVGCGCV
48+
```
49+
50+
Then if asked for Alice's plants, it should provide:
51+
52+
- Violets, radishes, violets, radishes
53+
54+
While asking for Bob's plants would yield:
55+
56+
- Clover, grass, clover, clover

# Introduction
2+
3+
The kindergarten class is learning about growing plants.
4+
The teacher thought it would be a good idea to give the class seeds to plant and grow in the dirt.
5+
To this end, the children have put little cups along the window sills and planted one type of plant in each cup.
6+
The children got to pick their favorites from four available types of seeds: grass, clover, radishes, and violets.
