function F N - fib (n) %The fib function uses a while loop to find the n'th Fibonacci %The input must be a positive integer if (length (n) >1 n2 else %Initialize F 1 %Initialize F 2 F3=F1+F2; F1=F2; F 2F 3; %Calculate the Fibonacci number %Change F 1 %Change F 2 %Decrement n end FN=F3; Return the F1bonacc number end end Question 1: How Fibonacci number is calculated in fib function
