Question: If you have a sorted array of 1000 elements, how many iterations will binary search take at most?

Options:

Correct Answer: 10

Solution:

Binary search will take at most log2(1000) which is approximately 10 iterations.

If you have a sorted array of 1000 elements, how many iterations will binary search take at most?

Step 1: Understand that binary search is a method used to find an element in a sorted array.
Step 2: Know that binary search works by repeatedly dividing the search interval in half.
Step 3: Realize that with each iteration, the number of elements to search through is halved.
Step 4: Identify that the maximum number of iterations needed can be calculated using the formula log2(n), where n is the number of elements in the array.
Step 5: In this case, n is 1000, so we need to calculate log2(1000).
Step 6: Use a calculator or logarithm table to find log2(1000), which is approximately 9.97.
Step 7: Since we can't have a fraction of an iteration, we round up to the next whole number, which is 10.
Step 8: Conclude that binary search will take at most 10 iterations to find an element in a sorted array of 1000 elements.

Binary Search – A search algorithm that finds the position of a target value within a sorted array by repeatedly dividing the search interval in half.
Logarithmic Complexity – The time complexity of binary search is O(log n), which indicates that the number of iterations grows logarithmically with the size of the input.
