I mean, if structure is O(1) for low N, it’s still O(1) for high N. If O “changes” from 1 to N with size then it’s never been 1. All I’m saying

“if it’s big”

is not how you identify correct O

Be me, have 15 items. Use any structure with any O. Latency still low

That’s not how Big O works

It’s all nice and cool but wtf is that road sign. Who the hell going to pay attention to grey sign which doesn’t even look like road sign while driving on what looks like 30 km/h road
