very late, but I did the same. 19 for " does not play banjo" and 1 for null termination

I just had the same issue, I utilized the global counter you suggested and
made it print out my hands after it got above 100 counts. The test at 120 is the following:

A,2,3,4,5 vs 9,10,j,q,k.. both are straights.
Most likely you are doing the same mistake as I was and comparing the highest of each straight.
But, here the ace is actually 1 not 14. That means K(13) > 5.

I know this is late, but I hope this is helpful to you.

I might be a bit late here, but here it is:

since the function is given as:
Data* sqInRect(int lng, int wdth) {};

you must return a pointer to the struct. You have two options.

initialize with a pointer:

Data *output;
...
return data;

or return the pointer to your struct.

Data output;
return &data;
