1. # What Is Pre-Requirement For Input To Binary Search To Implement

When you’re looking for a specific item in a large data set, it can be difficult to find. That’s where binary search comes in handy. This algorithm allows you to quickly scan through a data set and find the item you’re looking for. In this blog post, we will explore what is a prerequisite for binary search to implement and how it can help you in your everyday life. by understanding these prerequisites, you can make better decisions faster and save time.

## What binary search is

Binary search is a search algorithm that uses two indices to locate the searched item. The first Index is used to locate the largest value in the list, and the second Index is used to locate the smallest value in the list. This process is repeated until either a match is found or all values have been searched.

## What pre-requirement binary search has

The binary search algorithm is a pre-requisite for many sorting algorithms, as it can be used to find the desired element in a sorted list. Binary search requires two pieces of information: the location of the desired element and a comparison value. To perform binary search, first determine the location of the desired element in the sorted list using its position value. Next, use this value to calculate a new comparison value that is larger than but less than the current comparison value. If the new comparison value is smaller than the current comparison value, then locate the desired element at its current position in the list and set the new comparison value to this location. If the new comparison value is larger than the current comparison value, then locate and set the new Comparison Value equal to halfway between these two values (inclusive). Continue performing this process, doubling or halving each Comparison Value as needed until you reach either the desired element or an end of list condition.

## What is the difference between pre-requirement and post-condition

Pre-requisite means something that is necessary but not sufficient for the accomplishment of a particular task. For example, pre-requisite software is needed in order to run a certain application, but the application itself is not required. Post-condition means something that occurs after a pre-requisite has been met and enables the accomplishment of the task at hand. For example, post-condition software is needed in order to use an application, but the application itself is not required.

## How to implement binary search

Binary search is a simple algorithm that can be used to find a specific object in a sorted array or list. In order to implement binary search, you will need the following pre-requisites:

1) A sorted list or array of objects.
2) A comparison function that can determine whether two objects are equal.
3) A search key that identifies the desired object.
4) The ability to loop through the list or array and compare each object in turn.
5) The ability to stop searching when the desired object is found.
6) The ability to return an iterator that points to the location of the desired object in the list or array.
7) The code below demonstrates how binary search can be implemented using these pre-requisites:

public static < T > T find(T obj1, T obj2) { // Sort the objects according to their values using a provided comparator() // We will use this comparator later on when we perform our binary search int lod = 0 ; for ( int i = 0 ; i < obj1.GetIntValue (); i++) { lod = obj1.CompareTo (obj2, null ); } if (lod != 0 ) break ; } return lod; }
