Just a general suggestion, try adding a few print statements to give
you a better idea of the internal state of the code.  For example:

def factorial(x)
  puts "factorial{#{x})"
  . . .

def power(a,b)
  puts "Entering power():"
  p a, b
  . . .

def add(k)
  puts "#{Time.now}\tadd()"; p k
  . . .
  i=i+1
  if (i==k) then
    puts sum
    . . .
  else
    p i
  end
  . . .
