Create the pascal triangle

Pascal's Triangle is a triangular array of binomial coefficients. It is constructed by starting with 1 at the top (Row 0). Each subsequent row begins and ends with 1, and every other number in a row is the sum of the two numbers directly above it in the previous row.

Here are the first 7 rows of Pascal's Triangle:

Row 0: $1$
Row 1: $1 \quad 1$
Row 2: $1 \quad 2 \quad 1$
Row 3: $1 \quad 3 \quad 3 \quad 1$
Row 4: $1 \quad 4 \quad 6 \quad 4 \quad 1$
Row 5: $1 \quad 5 \quad 10 \quad 10 \quad 5 \quad 1$
Row 6: $1 \quad 6 \quad 15 \quad 20 \quad 15 \quad 6 \quad 1$
