Have you ever felt a requirement of duplicate keys and value pairs in a dictionary? Sounds like crazy!!! But yes few days back I required to have a map/dictionary with multiple entries of same key with different values and then performing some operation like groupby and get the count blah.. blah... So I couldn’t use the Dictionary object to fulfill my requirement as below is what you’ll get if you try to insert multiple keys inside a normal Dictionary object.
