How to display boolean results in terms of integer [duplicate]

Question

I have the following array

a = []

When I call a.empty? It will return true. But I want the same result in Numeric that is 1(In ruby 1 means true and 0 means false).

I know one scenario by using ternary operator

a.empty? ? 1 : 0

I want the same result without using any operators or if else conditions.

0

In ruby 1 means true and 0 means false

This is simply not true (pun intended). 0 is true as well as 1. Try it out.

The only falsy values in ruby are nil and false - that's it. So, an empty string is true, empty array is true, 0 is true etc.
