What is worst case and average case complexity of linear search algorithm with explanation?
For a list with n elements, the expected cost is the same as the worst-case cost, which is O(n). The average cost will be O(n/2). However, if the list is ordered by probability and geometrically distributed, the complexity becomes constant, O(1). Compare with a binary search which has a cost of O(log n).

The time complexity of the sequential search algorithm is?
O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
Which algorithm is slowest and why?
An algorithm that takes infinite time is the slowest. If the time complexity is O(infinity) then the algorithm may never produce a result. Algorithms with O(infinity) complexity are of no practical use whatsoever, other than to demonstrate how not to write an algorithm. As an example, consider an algorithm that sorts elements in an illogical manner, such as by shuffling the elements randomly and then testing to see if they are in the correct order. If you can imagine a deck of 52 playing cards you will know how impossible it is to shuffle the cards and get them all in the correct order. An algorithm doesn't need to have O(infinity) complexity to be considered useless for practical purposes. Bubblesort is a typical example of a useless algorithm. It has an average time complexity of O(n^2) (where n is the number of elements) which is considered reasonable for a small set of data but is impractical for large sets. However, it is not the time complexity that is the problem, it is the sheer number of swapping operations required upon each iteration. Insert sort has the same time complexity but is significantly faster on average because it has no swap operations. Even so, it has no practical uses because, like Bubblesort, it is only suitable for relatively small sets. For practical sorting purpose you need a non-linear algorithm with a time complexity of O(n log n) and, in this respect, hybrid sorts like Introsort win hands-down.

WHAT IS THE DIFFERENT algorithm of advantage and amp disadvantage?
Different algorithms do different things, so it makes no sense to compare them. For example, the accumulate algorithm is an algorithm which performs the same operation upon every element of a container, whereas a sorting algorithm sorts the elements of a container. Each specific algorithm requires a different set of concepts. An accumulate algorithm requires a data sequence with at least forward iteration and elements which support the operation to be performed, whereas a sorting algorithm generally requires random access iterators and elements that support a given comparison operation (such as the less-than operator).Even if two algorithms have the exact same time and space complexities, it does not follow that both will complete the task in the same time. For instance, the accumulate algorithm is a linear algorithm with a time-complexity of O(n) regardless of which operation is being performed. However, the complexity of the operation itself can greatly affect the actual time taken, even when the operations have exactly the same time-complexity. For instance, if we use the accumulate algorithm in its default form (to sum all the elements in a data sequence), the operation itself has a constant-time complexity of O(1). If we choose another operation, such as scaling each element and summing their products, it will take much longer to complete the algorithm (possibly twice as long) even though the operation itself has the exact same time-complexity, O(1).Consider the time-complexity of adding one value to another:a += bThis has to be a constant-time operation because the actual values of a and b have no effect upon the time taken to produce a result in a. 0 += 0 takes exactly the same number of CPU cycles as 42 += 1000000.Now consider the operation to scale and sum:a += b * 42Here, 42 is the scalar. This also has to be a constant-time operation, but it will take longer to physically perform this operation compared to the previous one because there are more individual operations being performed (roughly twice as many).The only way to compare algorithms is to compare those that achieve exactly the same goal but do so in different ways. Only then does comparing their respective time-complexity make any sense. Even so, time-complexity is merely an indication of performance so two sorting algorithms with the exact same time-complexity could have very different runtime performance (it depends on the number and type of operations being performed upon each iteration of the algorithm). Only real-world performance testing can actually determine which algorithm gives the best performance on average.With sorting algorithms, we often find one algorithm ideally suited to sorting small sequences (such as heap sort) and others ideally suited to larger sets (such as merge sort). Combining the two to create a hybrid algorithm would give us the best of both worlds.
What is big-o notation for describing time complexity of algorithm?
Big O notation allows to specify the complexity of an algorithm in a simple formula, by dismissing lower-order variables and constant factors.For example, one might say that a sorting algorithm has O(n * lg(n)) complexity, where n is the number of items to sort.Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. in memory or on disk) by an algorithm.
The time complexity of the sequential search algorithm is?
O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
Is the complexity of searching in a database logarithmic?
No, the complexity of searching in a database is typically not logarithmic. It is often linear or even higher, depending on the specific search algorithm and the size of the database.

What is the best search algorithm to use for an unsorted array?
The best search algorithm to use for an unsorted array is linear search. It involves checking each element in the array one by one until the desired element is found. This algorithm has a time complexity of O(n), where n is the number of elements in the array.

What is the linear time median finding algorithm and how does it work?
The linear time median finding algorithm is a method used to find the median (middle value) of a set of numbers in linear time, meaning it runs in O(n) time complexity. The algorithm works by partitioning the input numbers into groups, finding the median of each group, and then recursively finding the median of the medians until the overall median is found. This approach ensures that the median is found efficiently without having to sort the entire set of numbers.
