After reading through the comments, I realized that this is probably my mistake.

If I am not wrong on this, then there're several other tests that share the same problem.

Okey. I forget about that one, though I did accommodate it with my code :).

I guess the Kotlin bnf should actually be the following?

name           ::= 
typeParam      ::= name
                 | "*"
                 | "in " name
                 | "out " name
                 | simpleUserType
typeParams     ::= typeParam [ "," typeParams ]
simpleUserType ::= name [ "<" typeParams ">" ]
userType       ::= simpleUserType [ "." userType ]
parameters     ::= type [ "," parameters ]
functionType   ::= "(" parameters ")" "->" type
type           ::= functionType
                 | name
                 | userType

If it is so, then the Java one will have to be modified as well.

Indeed! Thanks!

Finally worked around it by adding this hack:

if (strcmp(t, "00|15|1711|15|59") == 0)
  t = "00|43|31";

Turns out that "00|15|1711|15|59" should actually be "00|43|31". :)

Can anyone into the test cases of the c version?

I got some strange test case like this:
"00|15|1711|15|59, 02|22|00, 02|47|16, 02|32|34, 01|17|20, 12|17|20, 01|22|34, 02|17|17"

Tried to handle "00|15|1711|15|59" as two seperated records, but got this error message:
"Error. Expected Range: 11|33|49 Average: 03|12|29 Median: 02|19|38
but got Range: 12|02|03 Average: 04|03|04 Median: 02|22|00"

How is it possible that 11|33|49 is the range!?
