Game Show's function interfaces

[fushar]

In Game Show practice task, contestants are required to implement
these interfaces:

int jackstart(int n, int k);
int jillstart(int n, int k);

But their return values are ignored in the grader's implementation. I
think they should be declared `void' instead of `int', to remove
confusion.

I agree. The Pascal version uses "procedure" and the C/C++ versions
should have used "void"

We'll pay careful attention to this for the IOI tasks. (Some of us
learned
C when there was no such thing as void, and its hard to teach old dogs
new tricks.)
