Is floating point error will be displayed after running but the answer is correct, and bosses,
CodePudding user response:
The factorial has a problem, will exceed the scope of the intIn fact it is not necessary to use array, as long as the two variables, a record minimum difference, a record second uninteresting facts value is ok, so it is not necessary to calculate the factorial
