A lady has fine gloves and hats in her closet- 18 blue-
32 red and 25 yellow. The lights are out and it is totally
dark inspite of the darkness. She can make out the
difference between a hat and a glove. She takes out an
item out of the closet only if she is sure that if it is a
glove. How many gloves must she take out to make sure she
has a pair of each colour?

• he least significant digits can be calculated, because they remain fixed! Starting at 1!+2!+3!+4! = 33, the units digit will remain 3 indefinitely. The sum at 9! will have the fixed last two digits (10! ends with two 0s).
  
  The most signigicant digits can be found in a similar way, pretty much done above, with 50! having the same leading digit as S. So
  S = 3. something...3 x 10^64
