    Question Random strings that don't repeat.. How many possible

    Hi all.. I have a math problem.. well two of them..

    Problem #1

    Given a pool of 29 different characters how many UNIQUE 5 character strings are possible?


    The pool is 3456789ABCDEFGHJKMNPQRSTUVWXY

    Stings can be anything like 33333 or 34567.. The only catch is that no two strings can be the same..

    Problem #2

    Given a pool of 15 different characters how many UNIQUE 10 character strings are possible?


    The pool is 123456789ABCDEF

    Stings can be anything like 3333333333 or 123456789A.. Again, the only catch is that no two strings can be the same..

    10 different ways to skin a cat and amazingly enough each and every one has the same result, the cat gets skinned! The same can be applied to code, so be nice and accept each others "preferences".
