Solution in RUBY Prog

In mathematics, Pascal's triangle is a triangular array of the binomial coefficients that arises in probability theory, combinatorics, and algebra. 1 1 1 1 12 1 1 3 2+1 1 Formula for Pascal's triangle is given by: n! 1 k! (n − k)! - where in denotes a row of the triangle, and k is the position of a term in the row. Create a function which takes a number and returns n top rows of Pascal's Triangle flattened into a one-dimensional list. Examples → pascals_triangle (1) [1] pascals_triangle (2) [1, 1, 1] pascals_triangle (4) → RUBY [1, 1, 1, 1, 2, 1, 1, 3, 3, 1]
