8 2 Principle of Locality

We share alot of courses in several fields in order to help other people learn what they are interested in.

Thank you so much sir. You do a much better job than Professor Mark at Michigan State University.

[@MuhammadBilal-tu4ld]

Nice explanation and out of the slides material, nice.

[@sampower7280]

Very straight forward and easy to understand explanation, thank you.

Maybe I heard wrong, but I heard the professor say sum += a[j] [i] [k] -- to increase spatial locality. I would change it to sum += a[i] [j] [k]

[@paldensherpa7612]

coool ... its a clean and easy explanation... thanks a lot brother..

[@riachevli8406]

so how to fix? fixed= a[i][j][k]; correct?

[@emilhaldan3198]

Someone correct me if i'm wrong:
i would say a[i][j][k] is correct. if you think about how data is stored in a 3D array, you essentially have an array, of arrays, of arrays.
For spatial locality, we wish to access the same array when iterating.
a[i] : will give us a 2D array
a[i][j] will give us a 1D array
a[i][j][k] will give us the k'th item of the a[i][j] array.
This will mean that for each i and j, the array a[i][j] is stored and cache, and all elements of the array may be accessed sequentially, while utilizing spatial locality.
Don't get fooled by the fancy wordsabove, i refreshed this 30 mins ago, and still doubt my self as i have an exam with it in a few hours :)
I think? 👀

Thank you for the video! Amazing

[@levyax1964]

Thank you, sir!

[@anupamarao3783]

can someone please explain how the 3 dimensional array program is fixed ?

[@sebastian-daquanglocknerjr1883]

think about how to access each array, and array of arrays sequentially
