Demo output:
----- Some statements -----
fib(i)
{
if (i < 3)
{
return 1
}
else
{
return fib(i - 2) + fib(i - 1)
}
}
mult(a,b)
{
if (b < 2)
{
return a
}
else
{
return mult(a, b - 1) + a
}
}
power(a,b)
{
if (b < 2)
{
return a
}
else
{
return mult(power(a, b - 1), a)
}
}
----- Syntactic Recognition with Computation -----
mult(5,3) = 15
2^10 = 1024
fib(7) (native) = 13
fib(7) (compiled) = 13
----- Elapsed runtime: fib(30) -----
