http://www.cprogrammingcode.com/2011/09/write-program-of-linear-search.html WebBinary search is used because it has a time complexity of O (N) for a sorted array. If we follow sequential access of Linked List, then it will take O (N) time to find the middle element. With this, the overall time complexity of Binary Search on Linked List will become O (N * logN). This will slower than linear search.
