Bit Manipulation in Python: Unset Nth Bit
In this video, we will write a program that takes an integer and
unsets the n-th bit in the binary representation of
that integer
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 unset the 1st bit, we should obtain
the binary representation:
1 0 0
This video builds on the idea present in the following video, where we used bit manipulation to determine if the nth bit of a number is set:
