Write a Python function that takes two lists and returns True if they have at least one common member.

Notes:

• Define a function which will accept two list parameters.
• Function should return True if both list contains at least one common element.
• Return False if no common element found.

Instructions:

• Program should be written in file build.py

• Function name should be solution.

• Input

   Type:  List
   Value: Case-I --> a = [1,2,3,4,5]
                     b = [5,6,7,8]
                    
          Case-II --> a = [1,2,3,4]
                      b = [5,6,7,8]
  

• Expected Output

    Type:  Boolean
    Value: True for Case-I and False for Case-II
