Ruby, let me ask you a conditional question.

Let me get to the point briefly.

When writing if statements in Python

For example,

The conditional statement if x in s is if x in s

I don't know how to express this in ruby.

I don't think Ruby supports expressions like xins

Please teach me how to operate the same way.

x = ["a", "s", "d"]

if x.include? 's'
    puts "hello world"
end

I haven't deepened the ruby, but there's a binary search method.
