BROWN 2002
There were different papers for different sessions.The paper had 5 sections, 5 * 8
= 40 Que's. totally
Section 1: Functions
Q: 1 - 8
Certain functions were given & based upon the rules & the choices had to be
made based on recursion. This is time consuming, but u can do it. Try to do it at
the end. Start from the last section.
L(x) is a function defined. functions can be defined as
L(x)=(a,b,ab) or (a,b,(a,b),(a,(b,b)),a,(b,b)).... two functions were given A(x) &
B(x) like
if l(x)=(a,b,c) then A(x)=(a) & B(x)=(b,c)
i.e., A(x) contains the first element of the function only.& B(x) contains the
remaining, except the first element.
then the other two functions were defined as
C(x) = * if L(x) = ()
A(x) if L(x) = () & B(x) != () & C(B(x)) otherwise
D(x) = * if L(x) = ()
** if B(x) = ()
A(x), if L(x) != () & B(x) != ()
D(D(x)),otherwise ;
Now the Questions are,
1 : if L(x) = (a,b,(a,b)) then C(x) is ?
(a): a (b): b (c): c (d): none
2 : if L(x) = (a,b,(a,b)) then find D(x)
same options as above
3 : if L(x) = (a,b,(a,b),(b,(b))) find C(x)
4 : find D(x)
5 : if L(x) = (a,(a,b),(a,b,(a,(b))),b) then find c(x)
6 : find D(x)
