# Sample List initializations
string = ['city1', 'class5', 'room2', 'city2'] 
substr = ['class', 'city'] 
substrRegEx = ['cit.+', 'class.'] 

# Driver code 
print(Filter(string, substr))               # Output : ['city1', 'class5', 'city2']
print(FilterOut(string, substr))            # Output : ['room2']
print(FilterRegEx(string, substrRegEx))     # Output : ['city1', 'class5', 'city2']
print(FilterOutRegEx(string, substrRegEx))  # Output : ['room2']
