In JavaScript, which is overall more efficient? Using IFs statements, Swith-Case, or K-V pair object with anonymous function? I have seen people using IFs- S-C and my self using K-V objects(something I picked from C# unfortunately).

As a programming newbie i think understanding logic was hard at the beggining, but the code it self was pretty easy.

Not sure if this is just me but rust is missing the random test cases and is erroring out when attempting.

I have to agree with others that this was very easy compared to the other 6 kyu problems I have done. This should probably be changed to 7.

I self approved and forgor to resolve the discourse, my bad

Oh sorry, for the wrong Tag!
And I found the issue with my code Thanks!

looks approved

a bug in your code is not a kata issue. please use the question tag to ask for help instead ;-) (also use markdown to format your code)

look closely at this line: how much memory are you allocating ? how much memory do you need ?

int *ptr = malloc(sizeof(int));

thanks a lot!

while ((cur_char = program[i]) != 'o')

infinite loop if there is no 'o'

no real random tests, integer overflow, input char * not const-qualified. all fixed, but I could not modify the prototype without invalidating previous solutions, so there is no way for the user to report his array's length

several things wrong here: if there are no 'o' in the input, you derefence malloc(0), this is UB; you also assume that malloc() will return zeroed memory, this is not always true
