Dot Product of Two Sparse Vectors

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.

Constraints:

• $n =$ nums1.length $=$ nums2.length

• $1 \leq n \leq 10^3$

• $0 \leq$ nums1[i], nums2[i] $\leq 100$
