PASCAL'S TRIANGLE

Pascal's triangle is a geometric arrangement of the binomial coefficients in a triangle. The rows of Pascal's triangle are conventional enumerated starting with rows, and the numbers in each row are usually staggered relative to the adjacent rows.

Given Instruction: On row 0, write only the number 1. Then, to construct the elements of the following rows, add the number directly above and to the left with the number directly above the and to the right to find the new value. If either the number to the right or left is not present, substitute a zero in its place. Example, the first number in htbe first row 0+1=1, whereas the numbers 1 and 3 in the third row are added to produce the number 4 in the fourth row.
