dont know sir,they gave aa value in solution,but my doubte is as per qs i calculated madeeasy(a-2) ,and whatever the final value came ,then i used that value of a in the next madeeasy(a-3) function,but they calculate both fn parallely,like madeeasy(4) madeeasy(3) parallely,my qs is that until and unless i calculate first function how did i move into the second function..and why did they use the value of a is 6 un both functions
