Apr 9, 2025 · Given a sorted array of Strings arr and a string x, The task is to find the index of x in the array using the Binary Search algorithm. If x is not present, return -1. Examples: Explanation: The String x is present at index 2. Explanation: The String “zz” is not present. The idea is to use Binary Search since the input array is sorted.
