Bit Manipulation in Python: Is Nth Bit Set?
In this video, we will write a program that takes an integer and tests whether the n-th bit in the binary representation of that integer
is set or not.
For instance, the binary representation of 6 is:
110
The least significant bit is the bit on the far right
of the binary representation and the most significant
bit is the bit on the far left. We order the bits as
b2, b1, b0
1 1 0
For our function, if we check the 0th bit, we should obtain
"False" as the binary value at b0 is 0.
Alternatively, if we check the 1st bit, we should obtain
"True" as the binary value at b1 is 1.
This video builds on the idea present in the following video, where we used bit manipulation to determine if a given number is even or odd:
