Hi guys,
Does anyone if for q6p4 is the input line by line or a long string?
if it is a long string then after the comment "//" does it include \n?
e.g (string form)
...
int wain (int a, int b){ int d=0; //this is a comment /n return d;}
or this form
int wain (int a, int b){ int d=0; //this is a comment return d;}... more »

Any release tests or blind tests for A6P3?
|
| |
The last sentence in A6 says that "For this problem only, all of the
Marmoset tests are public tests. There are no release tests or blind
tests. "
However, A6P3 does not have any release tests or blind tests either in
the Marmoset.
So, it this an error in A6 description OR a problem in the Marmoset?... more »

Any idea how to fix this one? I checked everything all the relocations
