Questions & Step-by-Step Solutions
What is the space complexity of the iterative binary search algorithm?
Step 1: Understand what space complexity means. Space complexity measures how much memory an algorithm uses as the input size grows.
Step 2: Know that the iterative binary search algorithm works by repeatedly dividing the search interval in half.
Step 3: Realize that in the iterative version, we only use a few variables to keep track of the current position and the search boundaries.
Step 4: Identify that these variables do not depend on the size of the input array; they remain constant regardless of how many elements are in the array.
Step 5: Conclude that since the amount of space used does not change with the input size, the space complexity is O(1), which means it uses a constant amount of space.
