Convert the C program below to LEGv8 assembly code. The value of n is stored in register X19. Store the sum in register X20. Assume all values are 64-bits. (printf and scanf function are not required to be converted in to assembly).

#include

int sum(int n);

int main() { int n, result;

printf("Please enter a positive number: "); scanf("%d", &n);

result = sum(n);

printf("The sum is %d.", result);

return 0; }

int sum(int number) { if (number!=0) return number + sum(number-1);

else return number; }
