Bit Manipulation in Python: Toggle Nth Bit
In this video, we will write a program that takes an integer and toggles 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 toggle the 0th bit, we should obtain the binary representation:
1 1 1
If we again toggle the 0th bit from the above representation we obtain
1 1 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:
