Given an array of words, print all anagrams together ?
Input : arr = ['cat', 'dog', 'tac', 'god', 'act'] Output : 'cat tac act dog god'
This problem has existing solution please refer Anagrams and Given a sequence of words, print all anagrams together links. We will solve this problem in python using List and Dictionary data structures. Approach is very simple :
- Traverse list of strings.
- Sort each string in ascending order and consider this sorted value as Key and original value as Value of corresponding key. Check if key is not present in dictionary that means it is occurring first time,
so map a empty list to Key and append value in it, if key is already present then simple append the value.
- Now each key will contain list of strings which are anagram together.
'cat tac act dog god'
