'''Fun with Anagrams: | |
QUESTION DESCRIPTION | |
Two strings are anagrams if they are permutations of each other. For example, "aaagmnrs" is an anagram of "anagrams". | |
Given an array of strings, remove each string that is an anagram of an earlier string, then return the remaining array | |
in sorted order. | |
For example, given the strings s = ['code', 'doce', 'ecod', 'framer', 'frame'], the strings 'doce' and 'ecod' are both | |
anagrams of 'code' so they are removed from the list. The words 'frame' and 'framer' are not anagrams due to the extra | |
'r' in 'framer', so they remain. The final list of strings in alphabetical order is ['code', 'frame', 'framer']. | |
''' | |
words = ['code', 'doce', 'ecod', 'framer', 'frame'] | |
# words_set = {''.join(sorted(word)): word2 for word2 in words for word in words if ''.join(sorted(word)) == ''.join(sorted(word2))} | |
# print(words_set) # nope | |
# for i, word in enumerate(sorted(words)): | |
# for x in range(len(words)): | |
# if sorted(list(words[x])) != sorted(list(word)): | |
# print(words[i]) | |
# | |
# result = {word: sorted(list(word)) for word in words} | |
# print(result) # nope | |
# word = 'code' | |
# print(sorted(word)) | |
# sorted_word = ''.join(sorted(word) | |
# print(sorted_word) | |
# word_set = {''.join(sorted(word)) for word in words} | |
def del_anagrams(lst): | |
# word_set = {''.join(sorted(word)) for word in words} | |
word_set = set() | |
result = [] | |
for word in lst: | |
if ''.join(sorted(word)) not in word_set: | |
result.append(word) | |
word_set.add(''.join(sorted(word))) | |
return sorted(result) | |
print(del_anagrams(words)) # It Worked!! |
