What does the (o==(0&&1)&&1) mean?

Answer 1

In short, it means, if 0 is equals to 0 And 1 as well as 1, the system will output a true.

Answer 2

0 represents false. 1 represents true. I'll show you how this is evaluated.

(o=(0&&1)&&1)
(o=(false)&&1)
(o=false)

The letter O isn't equal to false, or 0. The answer should be false as a result.

Answer 3

I saw this on a challenge question and didn't get what the answer would be, the options were true false and null
