WebApproach 3: No STL here, we use linear search where by we go all through the vector elements making comparisons between the elements and key k. Approach 1: Return index of the element using std::find() std::find() searches for an element equal to the value that is passed as a parameter and returns an iterator pointing to that element in the vector.
