Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.

In the main.asm file, you are to create a few arithmetic calculations using the following instructions: mov add sub Then after each expression is calculated, you will print the result using: mov rdi, XXX call print_num call print_lf The value of XXX will depend on which register your final result landed. Do this at least 3 times using only the registers ( rax, rbx, rcx and rdx). For example, if you wanted to print the result of 32 + 5 - 10, you could do something like: mov rax, 32 add rax, 5 sub rax, 10 mov rdi, rax call print_num call print_lf Remember that in order for the print_num subroutine to print your number, you must move the result into rdi.
