A Basic Just-In-Time Compiler

Monday’s /r/dailyprogrammer challenge was to write a program to read a recurrence relation definition and, through interpretation, iterate it to some number of terms. It’s given an initial term (u(0)) and a sequence of operations, f, to apply to the previous term (u(n + 1) = f(u(n))) to compute the next term. Since it’s an easy challenge, the operations are limited to addition, subtraction, multiplication, and division, with one operand each.
