For sorted array you can do it in O (logN) using a slightly modified binary search: Find the index of first occurrence of key, call it f. Find the index of last occurrence of key, call it l. If the key exists in the array l-f+1 is the answer. Finding the first occurrence: WebIn this lab, you will be implementing and analyzing the performance of two searching algorithms: Linear Search and Binary Search.
