# Serial and binary search algorithm

Binary Search finds the middle element of the array. The list does not need to be in any order. If the list is random, then linear is the only way 5.

If the list is large and changing often, with items constantly being added or deleted, then the time it takes to constantly re-order the list to allow for a binary search might be longer than a simple serial search in the first place. Next you open a page about halfway down the first half - the page has 'H'. Next you open a page serial and binary search algorithm halfway down the first half - the page has 'H'. Smaller, look further on.

Serial searching algorithm Set up the search criteria Examine first item in the data set If there is a match, end the procdure serial and binary search algorithm return the result with 'match found' If no match is found repeat with the next item If the last item is reached and no match is found return 'match not found'. No Is item less than criteria? The worst case being no match found and every item had to be checked. This speed disadvantage is why other search methods have been developed. A binary search, on the other hand, is when you open the book usually in the middlelook at the name on top of the page, and decide if the serial and binary search algorithm you're looking for is bigger or smaller than the one you're looking for.

I would like to add one difference- For linear search serial and binary search algorithm need not to be sorted. You want to find Samuel Jones in the local telephone book. Is Binary searching better than serial searching? A linear search looks down a list, one item at a time, without jumping. Disadvantages May be too slow over large lists.

Checks that middle value is greater or lower than the search value. Binary search requires the input data to be sorted; linear search doesn't Binary search requires an ordering comparison; linear search only requires equality comparisons Binary search has complexity O log n ; linear search has complexity O n as discussed earlier Binary search requires random access to the data; linear search only requires sequential access this can be very important - it means a linear search can stream data of arbitrary size. So the importantly you must serial and binary search algorithm sure the data is sorted before the binary search is started.

This is the simplest kind of searching. If the list is large and changing often, with items constantly being added or deleted, then the time it takes to constantly re-order the list to allow for serial and binary search algorithm binary search might be longer than a simple serial search in the first place. I would like to add one difference- For linear search values need not to be sorted. In this we check the middle element.

Also you can see visualized information about Linear and Binary Search here: So now Jones must be in the upper half of this section. May be too slow over large lists.
