WebJan 11, 2024 · Space Complexity: O (1) Solution 2: Binary exponentiation. Intuition: While calculating (n^k), binary exponentiation relies on whether n is even or odd. If k is even (n k) can be written as (n 2) k/2. As we can see that computation steps were reduced from k to k/2 in just one step. If k is odd (n k) can be written as n.
