check if two variable is not equal in Ruby

if a != b
  puts "a is not equal to b"
end

This code checks if the two provided variables, a and b, are not equal to each other. First, the code compares the two variables to see if they are not equal. If they are not equal, then the code will print out “a is not equal to b”. Otherwise, if a and b are equal, the code will not print anything. This is a short, effective way of quickly checking if two values are not the same.
