     Glad to hear it.  Just to verify, please post the output of
your Problem 3 solution for the string

	I solved those long time ago in C

... and state whether you are considering or ignoring letter case,
so we can check your answer.

I like problem 4, because of its well-quantified and concretely targettable
requirement: "as fast as possible".

1. Define an order in the symbol set of the string by a sort. 
2. Start from the smallest mapped by the ordered defined which will yield the maximum if reversed.
3. From the smallest string by the order defined, just generate the next until the maximum is reached.

I hate to answer  trivial questions!

     I'm sure you'll be happy to learn that you're tied for third

Please provide the email address of your instructor, so we can submit
our homework directly.

Also, please do something about your broken caps-lock key.

"Euler's Number"? Do you mean "the mathematical constant e"? Or
perhaps "a sequence En of integers defined by a specific Taylor series
expansion"?

If you mean /e/, then
a) the number starts with a /2/, not a /1/ (as in 2.718281828...),
b) Steve Wozniak published a solution to 116000 places, in 1981, and
c) /I/ wrote and published a C-language solution to 5000 places in the
1990s
What's so difficult about a /30 place/ solution?

It's been done. Many times over.

A little more difficult, but again, it's been done many times over.

Again, it's been done, many times. And it's simpler than e or pi.

So, what's your point? Or is this a sad attempt to get others to do
your homework for you?

That is Euler's number.

The confusion arises because e doesn't stand for "Euler". He chose it
because other mathematicians had already bagged a, b, c, and d for
other uses. The C programming language was named on the same system.

Except when one of them's ~2.781828 and the other one's ~0.577215665.
Better to include either the e or the gamma in the name to reduce 
ambiguity.

Hit #1 leads to
  http://en.wikipedia.org/wiki/E_%28mathematical_constant%29
  "The mathematical constant e is the unique real number such that the
value of the
  derivative (slope of the tangent line) of the function f(x) = ex at
the point x = 0
  is equal to 1."

Hit #2 leads to
  http://en.wikipedia.org/wiki/Euler_number
  "In the area of number theory, the Euler numbers are a sequence En
of integers
  (sequence A122045 in OEIS) defined by the following Taylor series
expansion:
    \frac{1}{\cosh t} = \frac{2}{e^{t} + e^ {-t} } = \sum_{n=0}
^{\infin}
    \frac{E_n}{n!} \cdot t^n\!
  where cosh t is the hyperbolic cosine."

I /believed/ that the OP meant #1 ("Euler's Number" aka /e/), but his
vague reference to the integer portion of the value being 1 lead me to
wonder if I was wrong.

I am talking about language features to be checked to be used as a tool to solve problems.

The subject line "OK. LETS START REAL PROGRAMMING IN C FOR PROBLEMS!!!" 
is a lie.  It should read: "a cretin who can't turn off his shift lock 
and engages in childish multiple exclamation marks wants someone else to 
do his homework."  Or just "Dihedral is a troll, please ignore."

Quite possibly, but it's also possible that the OP has seen the
recent spate of off-topic flaming and is making a clumsy attempt
to encourage actual discussion of C programming.

Perhaps we should consider following his example, if not his
typography.

Some advice to 88888 Dihedral:

1. Don't post in all-caps.  It's considered equivalent to shouting, and
is generally seen as rude.  Same for exclamation points.

2. Questions about actual problems you've encountered are more likely to
generate good answers than contrived puzzles (unless the puzzles are
particularly interesting, but frankly these aren't).

There was some library for big numbers written C. Of course, printing the big numbers won't be the same as printing native types. With other languages supporting big numbers  C with some libraries seems not attractive to novices.

If you're actually interested in particating here, then please
(a) format your text in lines shorter than 80 columns, preferably
around 72 and (b) quote some context from the article to which you're
replying (see 99% of the followups here for examples; Google Groups
can make this difficult, but the "old" interface isn't as bad as
the new one).
