# Serial and binary search program in c

If not you will be jumping all over the oceans without finding the value: Would you like to answer one of these unanswered questions instead? A binary search starts in the middle of a sorted array, and determines which side if any the value you are looking for is on.

Yes, the requirement that the input data is sorted is my first bullet point As an example, suppose you were looking for U in an A-Z list of letters index ; we're looking for the value at index Or if there is no value in the array finishes the search.

Bill the Lizard k Binary Search finds the middle element of the array. Dictionary analogy is better for me

We know that if we look at a random item in the data let's say the middle item and that item is greater than our target, then all items to the right of that item will also be greater than our target. Pick a random name "Lastname, Firstname" and look it up in your phonebook. The binary search would ask: Jump to the half way through the sublist, and compare again etc. Compare list[12] 'M' with 'U':

If we have elements to search, binary search takes about 10 steps, linear search steps. A linear search would ask: 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.

That "half" of the array is then searched again in the same fashion, dividing the results in half by two each time. Failing that, a general wikipedia, c2 or google serial and binary search program in c can answer may of these sort of questions. If not you will be jumping all over the oceans without finding the value: This is pretty much how humans typically look up a word in a dictionary although we use better heuristics, obviously - if you're looking for "cat" you don't start off at "M". If the value is bigger that what we are looking for, then look in the first half;otherwise,look in the second half.

If it is smaller, it gets the left side of the array and finds the middle serial and binary search program in c of that part. So the importantly you must make sure the data is sorted before the binary search is started. Pick a random name "Lastname, Firstname" and look it up in your phonebook. Linear Search looks through items until it finds the searched value. Also you can see visualized information about Linear and Binary Search here:

Mia Clarke 6, 3 41 It eliminates half the data at each iteration. Jon Skeet k

So you should never sort data just to perform a single binary search later on. Mia Clarke 6, 3 41 Jon Skeet k Please read the appropriate sections in your course material which, has hopefully, been selected and prepared by your instructor s.

Serial and binary search program in c 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 name you're looking for is bigger or smaller than the one you're looking for. Would you like to answer one of these unanswered questions instead? That "half" of the array is then searched again in the same fashion, dividing the results in half by two each time.
