Define a function reverseDict() that takes one parameter: - fansClub, a dictionary of key: value pairs, where the key is the name of a soccer fan and the value associated with that key is the list of soccer teams he/she is a fan off. The function returns a dictionary of key:value pairs, where the key is a soccer team and the value is the list of all names of its fans.

For example, fans = {'js':['Real Madrid','Juventus','Spain'], 'john': ['Real Madrid','France'], 'Alissa':['Roma','France']}

print(reverseDict(fans))

Output:

{'Real Madrid': ['js','john'], 'Juventus':['js'], 'Spain':['js'], 'France':['john','Alissa'], 'Roma': ['Alissa']}
