Please keep making these. Really helpful 👍

Do we need the last loop to return the dict values? Why don't we simply use return dict.values()

[soutrikmaiti]

Thanks for the lucid explanation and crisp answer. Waiting for more explanations to leetcode problems in Python!

[sunkari]

Thanks a lot for the videos with a great explanation. Very much appreciated. I'm learning a lot from your videos. Just one comment though. The background music is actually distracting :) otherwise great job.

[naramukuriht]

import collections
output = collections.defaultdict(list)
for i in strs:


print(output.values())

i took the logic from you, what do you think about the above solution? The time complexity is O(n).

[rahulsawhney]

your video is good but your background music is worst and distracting.

[yunfengzhao]

return dict.values() without the last for-loop, also got accepted

[_Sumeet]

Thanks for sharing :) Just curious if there's a more optimal solution.

Its 2020 and leet coding challenge day 6 is still the same question "Group Anagrams"

[navyamittal]

"unicode object has no object append"
i have the exact code but i'm getting the above error.
class Solution(object):
def groupAnagrams(self, strs):
"""
:type strs: List[str]
:rtype: List[List[str]]
"""
d = {}

for word in strs:
sortedword = "".join(sorted(word))

if sortedword not in d:
d[sortedword] = word #sortedwordkey #wordvalue

else:

d[sortedword].append(word)

return d.values()



could you please help?

[sarabaldinelli]

Thank youu, How can you make a program that counts these anagram groups?

[rajansharma]

is there any way to directly msg u...i have doubts regarding this question

[evelynanda-murillo]

what is the time complexity for this? 0(n)

[prachigupta]

i got error
ana={}
result=[]
for i in words:
a="".join(sorted(i))

if(a in ana):
ana[a]=[i]
else:
ana[a].append(i)

for i in ana.values():
result.append(i)
return result

i got key error

[harsha]

Can't you talk clearly? It's super hard to understand each and every words
