Dot Product of Two Sparse Vectors
Explore how to implement a SparseVector class to compute the dot product of two sparse vectors efficiently. This lesson teaches storing only non-zero elements and calculating products to optimize for sparse data using hash maps.

Statement
We must calculate the dot product of two given sparse vectors, nums1 and nums2.
Create a SparseVector class:
Constructor(): Initializes the object with the vector.
DotProduct(): Computes the dot product between the current instance of the vector and the other.
Note: A sparse vector is a vector that contains mostly zero values. Therefore, we should store the sparse vectors and calculate the dot product accordingly.
