Which searching algorithm is best for unsorted array?

Binary Search. Sequential search is the best that we can do when trying to find a value in an unsorted array.

Which searching algorithm is better linear or binary?

Binary search is more efficient than linear search; it has a time complexity of O(log n). The list of data must be in a sorted order for it to work.

Can linear search be used on unsorted arrays?

With regards to Linear and Binary searching, Linear searches are especially flexible because they can be used with both sorted and unsorted data while Binary searches are specifically used with sorted data. A linear search works by going through each element of the array one index after another sequentially.

Which searching algorithm you prefer to search an element in a linear array justify your answer?

Binary search

• Binary search is an efficient algorithm for finding an item from a sorted list of items.
• One of the most common ways to use binary search is to find an item in an array.

Which is more efficient searching algorithm?

Binary search is a more efficient search algorithm which relies on the elements in the list being sorted.

Which searching technique is used when we have unsorted list?

Linear Search is applied on unsorted or unordered lists, when there are fewer elements in a list.

What is the worst case complexity of linear search algorithm?

The linear search algorithm always results in worst case complexity of O (n) when element to be searched is last element in the array. Front and Back search algorithm for finding element with value x works the following way:

Why can’t I use binary search if the data is not sorted?

Binary Search exploits this property of sorting to ignore indices of an array. Thus, if data isn’t sorted, you cannot apply binary search. Is this a troll question?

What is in-place comparison-based sorting algorithm?

This is an in-place comparison-based sorting algorithm. Here, a sub-list is maintained which is always sorted. For example, the lower part of an array is maintained to be sorted. An element which is to be ‘insert’ed in this sorted sub-list, has to find its appropriate place and then it has to be inserted there.

How to find the last element in an array with O(n)?

A simple solution is to perform linear search. The linear search algorithm always results in worst case complexity of O (n) when element to be searched is last element in the array. Front and Back search algorithm for finding element with value x works the following way:
