Graham's number
G is defined in this way: u(3,n,1) = 3^n
u(3,1,m) = 3
u(3,n,m) = u(3,u(3,n-1,m),m-1)
[Knuth's up-arrow notation]
[Conway chained arrow notation] THEN g1 = u(3,3,4)
g2 = u(3,3,g1)
g3 = u(3,3,g2)
...
G = u(3,3,g63)
You are given that u(3,3,2)=7625597484987 to check your code.
Your task is to write a program/function that will output the value of G deterministically, given enough integer size and enough time.
