HI,
Im new to Java and I am trying to write a program that inputs an integer and finds the largest number less than the number entered. Im not sure if its a metadrome but here's an example, if I enter the number 1945 then the output should be 1789
Im new to the language so i posted in this section.

Thanks

I think there must be a bit more to the definition than that, otherwise you could just subtract one.

Here's one definition I found:

A metadrome is a number whose hexadecimal digits are in strict ascending order.
