# 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.

## Getting Started

For installation and learning resources, refer to the exercism help page.

## Running the tests

To run the test suite, execute the following command:

1 |
```
stack test
``` |

#### If you get an error message like this...

1 |
```
No .cabal file found in directory
``` |

You are probably running an old stack version and need to upgrade it.

#### Otherwise, if you get an error message like this...

1 2 |
No compiler found, expected minor version match with... Try running "stack setup" to install the correct GHC... |

Just do as it says and it will download and install the correct compiler version:

1 |
```
stack setup
``` |

## Running *GHCi*

If you want to play with your solution in GHCi, just run the command:

1 |
```
stack ghci
``` |
