PLEASE COMPLETE USING SCHEME LANGUAGE undefined The pattern you see below is

undefined

The pattern you see below is called Pascal's Triangle: 1 11 121 1331 1 4641 The numbers at the edge of the triangle are all 1, and each number inside the triangle is the sum of the two numbers above it. Write a function pascal with the following behavior: > (pascal 1) '((1)) > (pascal 2) '((1) (1 1)) > (pascal 3) '((1) (11) (1 2 1)) > (pascal 4) '((1) (11) (121) (1 3 3 1)) You may assume that the argument will always be a non-negative natural number. Output does not have to be pretty-printed, '((1)(1 1)(1 2 1)(1 3 3 1)) is a valid output of (pascal 4)
