String Comparing

[Harshil]

Hey! Friends After Some mind blowing tricks on google i approach with these solution!

# Function to print common characters of two Strings 
# in alphabetical order 
from collections import Counter 

def common(str1,str2): 
	
	# convert both strings into counter dictionary 
	dict1 = Counter(str1) 
	dict2 = Counter(str2) 

	# take intersection of these dictionaries 
	commonDict = dict1 & dict2 

	if len(commonDict) == 0: 
		print -1
		return

	# get a list of common elements 
	commonChars = list(commonDict.elements()) 

	# sort list in ascending order to print resultant 
	# string on alphabetical order 
	commonChars = sorted(commonChars) 

	# join characters without space to produce 
	# resultant string 
	print(''.join(commonChars)) 

# Driver program 
if __name__ == "__main__": 
	str1 = input('Please Type The First String:\n')
	str2 = input('Please Type The Second String:\n')
	common(str1, str2)
