Hi @cjyuan . Thanks for review. I have fixed conversion from hex to decimal.
I compared my other answers to self-check.
Is that answer enough?:

"How can you test if a binary number is a power of two (e.g. 1, 2, 4, 8, 16, ...)?
Answer: Test that it has exactly one 1."

Change looks good.

Answer: Test that it has exactly one 1."

Aren't you curious how to implement such a check in JS or in Python?

The approach involving log() function may not be 100% accurate because of floating point arithmetic, and is relatively slower than an approach that involves only one bit-wise and one arithmetic operations.
