Even commutative property is required to prove that the operation would give the correct answer right? Is there any operation has identity, self-inverse, and associative but not commutative 🤔

[@KarthikVippala]

Yeah I forgot to mention that, thanks for watching 👍😊

Hi Karthik! Since we are only interested in finding the number which occurs once, I think using a series of XOR operations alone should suffice. My understanding is that a counter (or any sequential for that matter) won't be needed - this is very similar to a binary to gray conversion, where you shift the bits and keep doing XOR. Also, the problem statement does not put a constraint on the max size of the elements which the array can have, so attention has to be paid here as well.

pls put google interview questions like these

[@shivakumarpujuri7196]

Superb question yar... Extraordinary work👍 Hoping to have more mind puzzling questions in further videos.

[@KarthikVippala]

Namaste 🙏, thanks for the support, sure will make more puzzles, good luck & great health 👍😊

@@KarthikVippala seems you are in bay area ..

Nope, 🇮🇳

[@swapnilvhatkar8868]

if each digit is represented using 4 bits, wont we need 4 xor to compare the data?

[@lavanyabalasubramanian5563]

Hey! Great video! Excellent animations!! Keep doing the great work! Also, where can we find these kind of questions for Digital design and verification interviews? Is there something like leetcode used by a lot of CS students?

[@KarthikVippala]

Thank you🙏, please check the source in description.

[@bhanutejaa1494]

Nice animation and good video.. 👍😊

[@KarthikVippala]

Thank you👍😊

[@kvssumakar2182]

Cool video, and nice style of animation But, You are not taking Array to store data in account. Also instead of taking a new register, you can reuse one of data register. Also is A^B^C == A^C^B ?

[@KarthikVippala]

Namaste sumakar, Yes we can use the same data register , it will reduce h/w, Yes in xor order doesn't matter. Good luck & great health 👍😊
