How to realize divisibility of substrings by java
Editor to share with you how java to achieve the divisibility of substrings, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
1406357289 is an all-digit number from 0 to 9 because it is made up of ten numbers 0 to 9, but in addition, it has an interesting property: divisibility of substrings.
Remember that D1 is its first number, D2 is the second number, and so on, we notice:
D2d3d4=406 is divisible by 2.
D3d4d5=063 is divisible by 3.
D4d5d6=635 is divisible by 5.
D5d6d7=357 is divisible by 7.
D6d7d8=572 is divisible by 11.
D7d8d9=728 is divisible by 13.
D8d9d10=289 is divisible by 17.
Find out all the all-digit numbers 0 to 9 that satisfy the same property and find their sum.
System.out.println (pandigitalPrime ())
Parsing:
First determine whether it is a full number, and then determine whether it is a prime number.
