[@deepak-pb2xt]

0 is the exception. Well, great content tbh. tysm

[@faizan346]

one correction it will give true even if the number is n = 0, which is not the power of 2 so, return (x && !(x&(x-1))); this will check for 0 and power of 2.

[@ritiktwopointo2691]

bits manipulation is really maical :) thanks again sir

[@anjandey6089]

Great explanation sir , in all videos , thankyou !!!

Thankyou Sir ❤️

[@shubhamsood1406]

Another approach is to count Set Bit and if set bit == 1, then it is a power of 2 else not a power of 2.

[@suyashlale7315]

but that would be O(log n) instead of O(1).

[@rohita6532]

@@suyashlale7315 just removing rmsb will also work, if it becomes zero it's true but in both approaches, we should check if the given number is zero or not if it is zero both approaches give true but it is not so a simple check in the starting would work there

[@bradbale1510]

Sir, im from mech branch. I've switched my career direction to IT and i am following pepcoding. Currently in 4th yr, unable to handle college subjects and minor project and coding together. was thinking to drop out(but bina degree ke job nahi), so just seeking suggestion as what to do? :)

[@Pepcoding]

bro, degree lelo jaise taise. System se itni ladai na karo. Ek cheez ka vishwash dilata hun, agar tumne 4th year mera sara youtube content kar lia to tumhe amazon mei place karana mai apni zimmedaari samjhunga. Aise ek DTU ka civil ka bacha amazon mei place kra chuke hain hum. Pepcoding ka sara youtube chaat jao, usme DS bhi ho jaegi, CORE bhi aur computer science ke projects bhi.
