# Pascal's Triangle

Compute Pascal's triangle up to a given number of rows.

In Pascal's Triangle each number is computed by adding the numbers to the right and left of the current position in the previous row.

## Setup

## Making the Test Suit Pass

Execute the tests with:

```
$ crystal spec
``` |

In each test suite all but the first test have been skipped.

Once you get a test passing, you can unskip the next one by changing `pending`

to `it`

.
