| Topics: |
Pascal's triangle is a triangle of numbers computed using the following rules:
- The first row is 1.- Each successive row is computed by adding together adjacent numbers in the row above, and adding a 1 to the beginning and end of the row.
Write a function which returns the nth row of Pascal's Triangle.
