                     It is based on recursive function
             M(a,b,c)- L(a) is if u delete 1st element from it             whatever is left.             N(a,b,c)-L(b) is 1st element of the list.             if (a,b) &a r two lists  then M(l1,l2) is ((a,b),a).               X(a,l)=a
                 =L(a)
                 =M(a,l)               y(a,l)=l
                 =L(b)
                 =M(l,a)            
Based on this          they gave 8 questions were there
