easyBinary SearchPattern: Binary Search
Binary Search Frequency Locator Solution
Problem Statement
You are given a sorted array of integers `frequencies` and a target frequency `target`. Implement a function to find the index of the `target` frequency in the `frequencies` array using binary search.
Examples
Example 1:
Input:[1, 2, 3, 4, 5], 3
Output:2
Explanation: The index of 3 in the sorted array is 2
Constraints
- The song IDs should be unique and non-negative.
- The song IDs are sorted in ascending order.
Time: O(log n) Space: O(1)
The optimized approach is to use binary search, which has a time complexity of O(log n).
