Explanation of Solution

Linear Search:

  • The Linear search also known as sequential search is a method to find an element in the given list.
  • The linear search matches with all the elements in the list until it finds the target element.
  • It checks sequentially to find an element of the list. It continues searching sequentially until a match is found in the list of elements. The search terminates when it reaches at the end of the list.
  • A linear search goes at a worst linear time when it needs to compare n times where the number of elements is n.
  • A linear search has an average case of “n/2” comparisons, if each element is equally likely to be searched.
