+# Instructions
+
+Your task is to, given a diagram, determine which plants each child in the kindergarten class is responsible for.
+
+There are 12 children in the class:
+
+- Alice, Bob, Charlie, David, Eve, Fred, Ginny, Harriet, Ileana, Joseph, Kincaid, and Larry.
+
+Four different types of seeds are planted:
+
+| Plant  | Diagram encoding |
+| ------ | ---------------- |
+| Grass  | G                |
+| Clover | C                |
+| Radish | R                |
+| Violet | V                |
+
+Each child gets four cups, two on each row:
+
+```text
+[window][window][window]
+........................ # each dot represents a cup
+........................
+```
+
+Their teacher assigns cups to the children alphabetically by their names, which means that Alice comes first and Larry comes last.
+
+Here is an example diagram representing Alice's plants:
+
+```text
+[window][window][window]
+VR......................
+RG......................
+```
+
+In the first row, nearest the windows, she has a violet and a radish.
+In the second row she has a radish and some grass.
+
+Your program will be given the plants from left-to-right starting with the row nearest the windows.
+From this, it should be able to determine which plants belong to each student.
+
+For example, if it's told that the garden looks like so:
+
+```text
+[window][window][window]
+VRCGVVRVCGGCCGVRGCVCGCGV
+VRCCCGCRRGVCGCRVVCVGCGCV
+```
+
+Then if asked for Alice's plants, it should provide:
+
+- Violets, radishes, violets, radishes
+
+While asking for Bob's plants would yield:
+
+- Clover, grass, clover, clover

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