Explanation:
Detailed explanation-1: -Finding a given element in an array of ‘n’ elements is referred to as searching in data structures. In searching, there are two types: sequential search and interval search.
Detailed explanation-2: -The Best Case occurs when the target element is the first element of the array. The number of comparisons, in this case, is 1.
Detailed explanation-3: -What is the worst case for linear search? Explanation: Worst case is when the desired element is at the tail of the array or not present at all, in this case you have to traverse till the end of the array, hence the complexity is O(n).
