Brilliant Solution

This is so cool! I learned several things with this function. Lots of ways I wasn't aware of with type coercion that makes this solution a lot cleaner than my own.

so beauty

The || c part is so good.

this solution forced me to question myself "How I got at 3kyu" 😶

Learned something new!

Awesome! I wasted a lot of memory on storing numbers :(

learn something new each day

gap yo'q

I would imagine there are some situation in which bitwise would be optimal... couldn't one then simply comment the code for the next developer whom may have to manage the code?

I wouldn't recommend using bitwise operators in production code they are really hard to understand and debug. I had hard time debugging production code that utilized bitwise operators.

great

~~: I learned something new today.
the while conditions, and the way u use res is very good but...
wew... took me a while to figure out what ur doing with c... true = 1, false = 0... useing that is brilliant.

Brilliant

But it already does that.
