I don't get it why my solution do not pass random test...
This kata is too easy for 6 kyu

Its because you are passing to target[i] pointer to const value and try to modify. Assign "some" memory on heap, copy context from y to this blocks and then do operations on this

tbh in C language this is on right lvl. Not to complicated to design solution, but you should well know how dynamic memmory works.

Of course... Damn it.
Now it's works. Thank you.

Also I would recommend, to cast pointer type that you allocate. Calloc, Malloc, Realloc <- all of this returns void pointer type to allocated memory.

Hi gues,
All sample tests passes, but i have issue with random tests. Every time when i attempt, random test results is "Caught unexpected signal: 6"
I do not have any idea how to debug this and cannot find issue in my code. Can someone help me ?
I have three different STDERR:
"double free or corruption (!prev)" or "free(): invalid pointer" or "free(): invalid size"

Definitelly to easy for 5kyu

Ohh really sorry, my bad. I read wrong error msg.

Ok, so you just can't write good random tests, and kata description. I get it.

There is issue with C++ translation in test4. m value is grather than n, so we should return "blank" string, but test expect different value.

and this is only one situation when m > n. Even random tests pass n grather than m.

I cant pass last random test in C.
Test Crashed
Caught unexpected signal: 6
What does that mean ? Can i look at the randomtests?
