i confused with my homework,i very don't understand when the programs solution without using pascal,when the theory says:
procedure or function mode
if(i>=2)and (j=1)then A:=A(i-1,2)
the question says when the program called A(4,7) why the answer is 509 explain the way!
i don't know solving the problem when i found this A:=(i-1,4(i,j-1)+1)and A:=(i-1,2)and like A(x-1,y)+1 and ext please help me to know solving this problem
