Consider the following recursive C function that takes two arguments:

unsigned int foo (unsigned int n, unsigned int r) {
  if (n > 0) return((n % r) + foo(n/r, r));
  else return 0;
}

What is the return value of the function foo when it is called as foo (345, 10)?

A company need to develop digital signal processing software for one of its newest inventions. The software is expected to have $$4000$$ lines of code. The company needs to determine the effort in person months needed to develop this software using basic $$COCOMO$$ model. The multiplicative factor for this model is given as $$2.8$$ for the software development on embedded systems. While the exponentiation factor is given as $$1.20.$$ What is the estimated effort in person months?
