That is why Sliding Window works:
- expand while the condition remains valid
- shrink when the condition becomes invalid

And because every element:
• enters once
• leaves once
the complexity becomes:
O(n)

That is the real intuition behind Sliding Window.

[Sayed Amaan Ali @sayed_amaan_ali]

Understand / Revise the Sliding Window pattern in one post 👇

Sliding Window exists because brute force wastes work (this becomes clearer with the example below).

In many array/string problems, we repeatedly calculate information for contiguous ranges (subarrays/substrings).

[Sayed Amaan Ali @sayed_amaan_ali]

Example:
[4,2,1] = 7 ✅ valid for condition (sum ≤ k), where k = 8
Expand right:
[4,2,1,7] = 14 ❌ invalid
Now we shrink from the left until validity is restored:
Remove 4 →
[2,1,7] = 10 ❌
Remove 2 →
[1,7] = 8 ✅

@Rohan2388 @yajnshri How do you know that this particular person has been doing it? What if the one receiving this punishment might not even be the rickshaw driver who is doing all of this stuff. While there should be strict actions against those who create trouble, it shouldn't be this action though

@Bajpaibriefing @gharkekalesh So you're going to solve it by creating more traffic?

(4/4) The Solution: Debouncing

Fire only when the user pauses before doing anything. The moment you do something new (like typing a new character in search), the countdown starts over.

Sending only minimal requests/calls and avoiding it each instance of the tied event.

#code

[Sayed Amaan Ali @sayed_amaan_ali]

debouncing in javascript is just teaching your code some patience

not every keystroke deserves a reaction. wait for the pause. then move.

honestly a life lesson too 🕊️.

But what is debouncing in JS? A thread to explain (1/4)

#javascript #debounce

(3/4) the browser and server get hammered with redundant work

This same problem appears anywhere a function is tied to a high frequency event like scroll, mousemove, keystrokes, etc.
