Four digit numbers with no repeats |
2010-01-02 |
|
Daniel pose la question :
I want to know how many different numbers there would be between the numbers
0000-9999 that do not have any numbers that duplicate or repeat in the number? For example
the first number would have to be 0123 and the last would be 9876 (I think) Thanks!
