Leetcode 231. Power of Two | Bit Manipulation & Math | Python Solution
⚡ Solve Leetcode 231 – Power of Two using Bit Manipulation and Mathematical Logic in Python!
In this problem, we determine whether a given integer is a power of two using two approaches — logarithmic check and bitwise tricks.
Problem Summary:
A number n is a power of two if there exists an integer x such that n == 2^x. We explore:
1️⃣ Mathematical Approach — Using log2 and ceil for exact power checking.
2️⃣ Bit Manipulation — Leveraging the fact that n & (n - 1) == 0 for powers of two.
What You’ll Learn:
Why powers of two have only one set bit in binary.
How to avoid floating-point precision issues.
Bitwise & operation optimization.
Clean Python code for both methods.
Step-by-step dry run with examples.
