[RUBY] Qiita article summary that solved the Stack Overflow problem that always sets (a == 1 && a == 2 && a == 3) to true

Can (a == 1 && a == 2 && a == 3) always be true?

I wrote a terrible article called Ruby script that makes (a == 1 && a == 2 && a == 3) true, so I have to make up for this problem. Make a note of the article that challenged. We have not confirmed the operation because the languages are diverse. The order is appropriate.

In terms of code golf, I feel that the 32 bytes I wrote are a pretty good line.

Update if there is an edit request.

What was solved

Mostly solved

Things I don't want to solve

Ruby script that makes (a == 1 && a == 2 && a == 3) true
