Is there any difference between "!=" and "!~" in Ruby?
ruby
Solution
The `=~` operator and its negative `!~` are for pattern-matching. It is overridden by Regexp and String to provide regular-expression pattern matching, but for numbers it is not implemented. This is why `2 =~ 3` gives `nil`, so `2 !~ 3` is `true`.
Problem
I was trying to play with the operators `!~` and `!=` in below code. But couldn't figure out such any differences. But I have doubt, If not so, why Ruby introduced them? ``` 2 !=3 # => true 2 !~ 3 # => true c= [1,2,3] # => [1, 2, 3] d=[1,4,5] # => [1, 4, 5] c != d # => true c !~ d # => true ``` Could anyone please help me here by saying if any difference between them ?
