How To Get The Opposite Binary

This post is mainly for those who are looking to get the opposite binary numbers programmatically. Here I will be explaining with Ruby, but this could work for all programming languages.

Let see the problem statement!!! If the binary input/value(‘0’ or ‘1’) passed to the method or function should return the opposite binary value.

Example:

• If the value “1” is passed to the method/function should be getting the response as “0”.
• If the value “0” is passed to the method/function should be getting the response as “1”.

Solution

# Ruby!
def get_opposite_binary(value)
   result = 1 - value
   puts "Input: #{value} ---> Output: #{result}" 
end
# Output:
get_opposite_binary(0) 
# Input: 0 ---> Output: 1
get_opposite_binary(1)
# Input: 1 ---> Output: 0
