Oh I forgot this rule. Thanks for reminding!

This was a great opportunity to come up with a creative solution!
It’s always interesting to see how others approach the same problem after you’ve solved it.
Thanks for this awesome kata!

very easy kata!
Hint: Just use by simple math formula to count the odd numbers.

C++

The resulting array shouldn't necessarily match anyone in the tests, a function just checks if the array is now wave sorted.

The vector content should stay the same

It can't be both together. If the function only checks if the array is wave sorted, it shouldn't check if it stays the same.

It's even worse: i've added

if(is_wave_sorted(v))
    return;

at the beginning of my function, and still it returns "The vector content should stay the same". So, my function only runs if the check function fails - and still the vector should stay the same?

This problem can be reduced to the set cover problem, which is NP-hard, looking at size of tests I can assume that reference solution uses some king of greedy approach, which do not guaranty optimal solution.
Example A = [3, 8, 8, 6, 7], B = [2, 2, 3, 5, 6], k = 6. My solution is 3. First thief can take from jars 1 and 4 second from 2, third from 3 and 5

Can the password be empty (eg: no 'T' at the end of directions) ? Can grid be 1x1 and/or can directions be empty (thus password would also be empty) ?

I'd like to translate the kata and I think these cases could be interesting but I don't know if I should implement them or not. I also think it could be added to the description.

Merged the fork with the fix.

Merged.
