JEST Sample Question-2
Consider the following function, defined by a recursive program: function AP(x,y: integer) returns integer; {if {x = 0 then return y+1} else if { y = 0 then return AP(x-1,1)} else return AP(x-1, AP(x,y-1)) } (a) Show that on all nonnegative arguments x and y, the function AP terminates. (b) Show that for any x, AP(x, y) > y.
