Very useful

[@LeetJourney]

Glad to hear that

[@priyanshusharma751]

are you referring pointers as c++?

[@LeetJourney]

No - when I referred to pointers in this video (e.g Sliding Window) and I was talking about setting one at the beginning and one at the end, I was simply referring to use an int variable to store indices of the array.
Example
leftP = 0
rightP = len(array)-1
Hope it’s clear now

@@LeetJourney yeah, its clear now. thanks. ❤️
