About the square root function

#1

what does mid=(s+e)>>1 means in the code int the video?

#2

@aslesha.j7 >> is the bitwise right shift operator. It results in dividing the number by 2. n >>2 means n/2. Bitwise operations are really fast, this is why it is being used instead of normal division.
So that line means mid = (s+e)/2

#3

but they have used (s+e)>>1 not (s+e)>>2

Hi @aslesha.j7

Yes you are right, actually how right shift operator (>>) works is

x >> y => x / (2^y)

So, that’s why when you have written (s+e)>>1 it will result in (s+e)/(2^1) which is (s+e)/2

here ^ represents power, (x^y) is x raised to power y.
