calculate permutation combination

Hi All,

I want to implement one logic like below.

Number: 345678987656733

If the user giving the input as 898765. I want to check the value is matched with the above value or not based on the below format.

The given input length is 6, It should check 6 numbers.

For example:
Combination         Result
345678           !=    898765
456789           !=    898765
567898           !=    898765
678987           !=    898765
789876           !=    898765
898765           =    898765 (Matched) Similarly it will check the remaining combination and return the result.

You can try String contains method to check if input matches with any continuous value in your actual number. 
String strNumber = '345678987656733';
String input = String.valueOf(input);

if(strNumber.conatins(input)){
//your logic
}
