The useless

int cmd = std::stoi(packet.substr(4,4));

was the problem, when an invalid base 10 command is received, an exception is thrown.

I won't try, but I'm sure all the solutions I'd tried were rigth

Thank you

Hi

"Caught unknown exception" unless I give a wrong result

I've tried a lot, lot of ways to no avail

sprintf, substr, append, ostringstream

Any hint?
thanks

Hi yhimanshu484

I think that you should ignore the in between position

Found it... I was not checking for one othe kind of null input

Hi,

What does

"should_work_for_edge_assertions
Test Passed
Test Crashed
Exit code: 0
Signal code: 11"

My code is working for empty string, having '/', '0', '9', ':', starting or ending with a digit....

Thank you, now it's working fine

Sorry, learning the rules...

C:

I have a working algorithm but I'm having trouble with returning the array. Commenting out the call to free() works fine with the example test. If not, I get an

*** Error in `/home/codewarrior/solution': munmap_chunk(): invalid pointer: 0x00007ffd94be9eb0 ***

int* nbMonths(int startPriceOld, int startPriceNew, int savingperMonth, double percentLossByMonth) {
int * result;
result = (int *) malloc(result);
...
return result;
}

void dotest(int startPriceOld, int startPriceNew, int savingperMonth, double percentLossByMonth, int *expr) {
....
//free(act); act = NULL;

Any advice?
