Why strrev function is not working at sololearn ide ?

Question

#include <stdio.h>
#include <string.h>

int main()
{
char s[50];
gets(s);
printf("%s",strrev(s));
return 0;
}

Answer 1

The thing is, strrev is only defined on a windows machine.
Sololearn runs the code on a linux machine, however, if you try to run the code often enough you will eventually run it in a windows machine ( for some reason ) and then it will work.
I guess Rowsej just got lucky there, because it took me around 20 tries.
