Write a Scheme program for print-plot of function f(x) = 15|sin(0.2x)|

Define the function f that returns f(x)

Define the function xlist(n) the returns the list (1 2 3 ... n)

Define the function ylist(n) that returns the list (f(1) f(2) f(3) ... f(n)

Define the function point(y) that displays a line with max(0, y-1) spaces followed by '*'

Define the function graph(lst) which uses the function point to plot one line with point for each value of

the list lst
