This story kept my interest throughout with non-stop action Top LeetCode Interview Questions. Facebook, Amazon and Big The best and most accurate approach would be to use bit manipulations: (n & (n-1) == 0) and n != 0 Explanation: every power of 2 has exactly 1 bit set to 1 (the bit in that numbers log base-2 index). So when subtracting 1 from it, that bit flips to 0 and all preceding bits flip to 1. That makes these 2 numbers the inverse of each other so when AND-ing them, we will get 0 as the result.For SDE interns and new grads, this will be the last part of the online assessment (OA 3).
