How do you search std::vector?

Finding an element in vector using STL Algorithm std::find() Basically we need to iterate over all the elements of vector and check if given elements exists or not. This can be done in a single line using std::find i.e. std::vector::iterator it = std::find(vecOfNums.

find(): Used to find the position of element in the vector. Subtract from the iterator returned from the find function, the base iterator of the vector .

The simplest solution is to count the total number of elements in the vector having the specified value. If the count is nonzero, we have found our element. This can be easily done using the std::count function.

If element exists in the vector, then it will return the iterator pointing to that element. Whereas, if element does not exist in the vector, then it returns the iterator pointing to the end of vector. This generic function can be used with any type of vector to check if contains an element or not.

vector::empty() empty() function is used to check if the vector container is empty or not.

Vector search can be applied across a multitude of applications, such as web text search, multimedia + image search, recommendations, and many more. As an example, we’ve used vector search to power an image similarity search application across multiple image databases, such as animals, cats, and dogs.

In order to use binary search, you may use qsort to sort the vector first to guarantee it is ordered. I use something like this…

Basically we need to iterate over all the elements of vector and check if given elements exists or not. It accepts a range and an element to search in the given range. If element is found then it returns an iterator to the first element in the given range that’s equal to given element, else it returns an end of the list.

Vector search uses deep learning models to encode data sets into meaningful vector representations, where distance between vectors represent the similarities between items.
