Webint Search_Seq (SSTable ST , KeyType key ) {ST . R [0]. key = key ; //Put the keyword to be searched into the header for (i = ST . length ; ST . R [i ]. key != key ;--i ); //At this time, only one comparison is required for each loop return i ;} WebSearch success: search probability is the same and search in order. Under this premise, ASL=(n+1)/2. Time complexity: O(n) Advantages: simple algorithm, suitable for sequential structure and chain structure regardless of whether the keywords are in order. Disadvantages: the average search length is large and the search efficiency is low. 2.
