# Difference between serial search and binary search

The table must be sorted for binary search. It eliminates half the data at each iteration. If it is smaller, it gets the left side of the array and finds the middle element of that part. This means that we only need to look at the left part of the data. Linear Search looks through items until it finds the searched value.

Serial searching makes no assumption at all about the list difference between serial search and binary search it will work just as well with a randomly arranged list as an ordered list. Yes, the requirement that the input data is sorted is my first bullet point Join Stack Overflow to learn, share knowledge, and build your career. Linear Search looks through items until it finds the searched value. A linear search is starting at the beginning, reading every name until you find what you're looking for.

It eliminates half the data at each iteration. A binary search is when you start with the middle of a sorted list, and see whether that's greater than or less than the value you're looking for, which determines whether the value is in the first or second half of the list. A criteria is set up before the search begins.

Time both methods and report back! Dictionary analogy is better for me If no match is found, then the process will return the appropriate message. Binary search requires the input difference between serial search and binary search 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.

We can leverage this information to decrease the number of items we need to look at to find our target. Not affected by insertions and deletions.

Jon Skeet k Serial searching makes no assumption at all about the list so it will work just as well with a randomly arranged list as an ordered list.

Repeat this procedure until you find the page where the entry should be and then either apply the same process to columns, or just search linearly along the names on the page as before.

In complexity terms this is an O difference between serial search and binary search n search - the number of search operations grows more slowly than the list does, because you're halving the "search space" with each operation. Disadvantages May be too slow over large lists. With dictionary approach, the take away is sorting.
