OMG! This is the clearest explanation I have seen! Really hope you keep making videos!
Really glad to hear that
The count array gets rid of the permutation problem and the sliding window trick gives a nicely scalable iteration. Edit: watched to the end... Nice
This is an epic explanation! Thank you!
Glad to hear it, thanks a ton!!
It's easy to understand, thank you!
Simple and elegant, thank you for the great video
You're very welcome :)
Really helpful and well explained
Glad to hear it, thanks a ton!
just do this
class Solution:
def checkInclusion(self, s1: str, s2: str) -> bool:
check = Counter(s1)
temp = {}
k=len(s1)
for i in range(len(s2)):
if i
Good video
Why we build up s2 count array in the first for loop? Why can't we just build it from start in the second loop?
It's just easier this way iirc
