isPrime?

1. Automate Community
2. Education

*Note*
The program is same with:
category/education/找質數

*Updated*
> Add clipboard to sort your find number history.
> Add judgment: enter number must >= 2, or illegal, and you must re-enter.
> Corrected result display format.

*Introduction*
Enter a number,
and the program will tell you what is or isn't a prime.

*Hints*
> Considering your phone performance, recommanded you should enter less than 11 digits number.
> Cause using regex will let progress slower (very slow!), so enter number of zero at the beginning is legal. (But result will correct it.)
