When would a linear search be preferable over a binary search?

linear search be preferable over a binary search because In binary search the input data must be sorted before searching but in linear search input data need not to be sorted .

As input data need not to be sorted in linear searching so the complexity of linear sorting is  O(n)  but in binary search if input data is not sorted then firstly be sorted the data then after that it perform searching so the complexity of binary search if input data is not sorted is O(nlogn+logn)

Their are some important points linear search over binary search

linear searches searches the data linearlly so it perform equality comparison and binary searches the data randomly so  perform ordering  comparison.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
