| # Instructions | ||
|
|
||
| Given a diagram, determine which plants each child in the kindergarten class is | ||
| responsible for. | ||
|
|
||
| The kindergarten class is learning about growing plants. | ||
| The teacher thought it would be a good idea to give them actual seeds, plant them in actual dirt, and grow actual plants. | ||
|
|
||
| They've chosen to grow grass, clover, radishes, and violets. | ||
|
|
||
| To this end, the children have put little cups along the window sills, and | ||
| planted one type of plant in each cup, choosing randomly from the available | ||
| types of seeds. | ||
|
|
||
| ```text | ||
| [window][window][window] | ||
| ........................ # each dot represents a cup | ||
| ........................ | ||
| ``` | ||
|
|
||
| There are 12 children in the class: | ||
|
|
||
| - Alice, Bob, Charlie, David, | ||
| - Eve, Fred, Ginny, Harriet, | ||
| - Ileana, Joseph, Kincaid, and Larry. | ||
|
|
||
| Each child gets 4 cups, two on each row. | ||
| Their teacher assigns cups to the children alphabetically by their names. | ||
|
|
||
| The following diagram represents 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 |
