INPUT For the above input, what's the correct output?

Use regex to handle the escape chars,
the problem becomes a piece of cake.

Accepted. Funny to create C by Java.

After a few times of runtime error, I think the testing data of this problem is badly formatted, and the description is badly written.

Don't trust the description and the sample input format.

When it says the first line contains something it can mean the first line is blank.
When it says there is ...

For case 4, my output is
3
1 2 4

It can be confirmed easily by manual checking.

I think 1 9 4 is also correct

Here is my version of output:

How to solve
1. do a character count for each existing chars in the input string. Store the counting result in a map-like structure, mapping each char to its count. You get an array of the map structure.
2. sort the array by the char, in descending order.
3. sort the array by the count, in ...

Does 11602 also has a special judge? I get PE with unknown reasons in this problem.

It is an interesting problem but the judge's behavior is too strange.

I've tried out all possible newline/no-newline options but it is always PE.
I write it in Java and all outputs are done by System.out.println(keyOrder);

It seems there is no tricky output requirement.
Does PE mean something ...
