Google Coding Interview Question - Bit Manipulation - Different Bits sum pairwise

[@dpxy1599]

Excellent question

[@smrutiranjan3623]

Very nice explanation

[@SCALER]

Thanks for your kind words Smruti :)

[@saicharan-dn3jz]

Super Clean And Neat, Good Explaination!

[@hackytech7494]

Thanks. Nice explanation. But i didn't understood that why we are iterating for 32 times in outer loop. Can anyone explain me please

[@JaideepKumarSingh14]

Because there are 32 bits in a number

[@bhopalsingh4102]

I think we should take modulus at the time of adding itself. i.e. in this statement "ans+=2*count*(A.size()-count);" otherwise it may give wrong answer...

[@SohanonYoutification]

ans is long long int datatype which is 64 bits so not needed to do that.

[@harishkandikatla9791]

Excellent explanation! Keep on posting these kinds of videos!!

[@adityasingh7288]

the plane took off

[@KD-xi9wu]

How (A.size()-count ) give count of number of zeros????

[@PrathamGupta2408]

Nice explanation Paridhi 👌

[@shourabhpayal1198]

good vid. Pace can be improved plus example could have been explained more clearly and faster.

[@Sampathgayani]

I think this is important.... This pseudo-code is written using C++ .... Not java... if you don't know the differences, you may get confused. It would be helpful if Paridhi mentioned this. Also if she elaborated the pseudo-code a little more how it matches the previous explanation. Maybe she thought certain things are obvious... :) but still, we are not there :D @Paridhi.... Thank you so much... great work!

Your voice is sweet

[@AradhyaMudgal]

Awwwww

[@sonumahto1364]

Thank u so much.

[@balaganesh_spk]

Why MOD is required at end and why mod with 10000007??

[@NamrataBilurkar]

That is asked in the question

[@shivanktripathi4661]

The first test case is wrong for 2,7 the answer should be 4 because f(2,7) + f(7,2) = 4

[@TheDarkaqua]

so for the given question i.e [1,3,5] is the answer 8 or 16? correct me if i'm wrong!

[@TheDarkaqua]

I wrote the code, the ans comes out to be 8.

[@sibanshpal8536]

ans is 4*2 = 8

[@Sampathgayani]

It is asking for the diff bits... not the equal bits... I made the same mistake and realized it later :)

[@dhanorammardi646]

In 10.58, instead of left shifted it is right shifted.

[@ankitgoyal8556]

Loved it, thank you I feel like the sound is bit low.

[@SHASHANKRUSTAGII]

handwriting

[@salmankhatik4985]

too confusing

[@shrutisharma9297]

why is f(5, 1) different from f(1, 5)?

[@adityakrishna11]

its not

[@ayushgarg5929]

Very long video...it could be easily explained in 5 minutes

[@ashutoshbisht8563]

your low voice is totally irritating .so please mam make your voice loud

[@gunahawk6893]

dude stfu

[@sibanshpal8536]

Great explanation..

[@dushyantsingh2624]

Thanks a lot
