Not an issue

maybe first and last string wouldn't consist of spaces

@dinglemouse: There is also a nice variation of this great kata: https://www.codewars.com/kata/next-smaller-number-with-the-same-digits

@Mrityunjay Bhardwaj: It was me, who translated this kata to Java. As you can see below: There was a comment "Java-Translation kumited!"...

There is no problem in the kata. (25 warriors did it in Java until this moment). And like dinglemause said it before: There is no biggertest for 1286608618.
I tested it last minute, if such test would be succeed: Without problems with the solution.

Have you you written the input value to the console for checking? Maybe your code changed a value in a wrong way?

Look a few comments down below: Steffen is the one who translated it and he has certainly a much better command of Java than me.

@Mrityunjay Bhardwai.

FYI - I have just moments ago successfully completed the Java version of this Kata. There are no problems at all.

You said your code failed on a Java test called BiggerNumber with input of 1286608618.

• But there is no such test in the Java JUnit. (For Java the test is called biggerTests)
• And there is no such test input same as that either either

So I don't know what you are looking at... but it not the current Java submission test cases

@dinglemouse yes, maybe you are right.... but i dont have an authority to check the Junit tests complectely.... and @GiacomoSorbi i cant uderstant what do you mean by "Java translator comment" (do u mean the one who is a JAVA programmer and solved it before?) sorry i am new here.....

@Mrityunjay Bhardwai, I know you think you are returning the correct result but it might be worth triple-checking that it's not you returning that -1. Sometimes the JUnit tests some of Katas are written wrong and the actual/expected values are reversed. It can lead to confusing situations like this.

(Not saying that it the case here... but it might be)

Because the input number is "1234567890"..... So the next number using the same digits should bE : "1234567908" But insted your code returns "1234567980 which is the second next biggest..... Not the "next" biggest!

Hope it helps.... :)

1234567980 should equal 1234567908
But 123467908 is smaller than 1234567980. Why 1234567908 is next bigger number, when its smaller. My code can't pass the test.
