I need help with Kata Convert a String to a Number. My code won't compile and I can't find the reason why. I compared my code to Instructio and Sample Test again and again, debugged it in IntellyJ, where it runs without problems. It's driving me crazy, not to find the problem. If anybody could help me,I'ld be very grateful.
The language is Java.

c#:
the function Ipow() called in TestRandomNumbers() in Test Cases (but not in Test or Attempt) doesn't seem to be correct, it raises an OverflowException if b is rather big. Could Test Cases get updated?:

 private static int Ipow(int b, int e)
 {
     int p = 1;
     for (; e > 0; e >>= 1)
     {
         if ((e & 1) == 1) p *= b;
         b *= b;
     }
     return p;
 }

Why return c() for input integer(0) don't work in R?

There is a mistake in random tests in ruby. In one point it's expected the code to pass with really big numbers, over 2 billions, at second poing it's expected to return nil for number over 1 billion becouse its to big number.

nitpick: a minor typo in the decsription check whet[H]er a given

A little disappointing that the tests are so undemanding. Even the very naive solutions can pass.

What is the maximum possible value for "n"?

Similar to this issue but in Python:

Assertions are placed in conditional blocks what causes that they are sometimes not executed, making test output incomplete.
