Python program to find the size of largest subset of anagram words

Given a lowercase array. Our task is to find the size of the largest subset of string which is an anagram of each other. Anagram of the string means one string is an anagram of another if the second is simply a rearrangement of the first. Here we can solve this problem quickly in python using Counter() method.

For example, the strings 'python' and 'typhon' are anagrams.

Algorithm

Step 1: Split input string separated by space into words.
Step 2: sort each string in given list of strings
Step 3: now create a dictionary using a counter method which will have strings as key and their Frequencies as value.
Step 4: get maximum value of frequency using max function.

Example code

# Function to find the size of largest subset 
# of anagram words from collections import Counter
def largestana(str1):
   # split input string separated by space
   str1 = str1.split(" ")
   # sort each string in given list of strings
   for i in range(0,len(str1)):
      str1[i]=''.join(sorted(str1[i]))
   # now create a dictionary using the counter method
   # which will have strings as key and their
   # frequencies as the value
   newstr1 = Counter(str1)
   # get maximum value of frequency
   print ("The Size Of largest subset of Anangram word is ::>",max(newstr1.values()))
   # Driver program
   if __name__ == "__main__":
      str1 = input("Enter the string ::>")
      largestana(str1)

Output

Enter the string ::>qwe ewq rty ytr ytr ytr
The Size Of largest subset of Anangram word is ::> 4
