Solution: Dot Product of Two Sparse Vectors

Explore how to calculate the dot product of two sparse vectors by focusing only on nonzero elements. Understand how to use hash maps to store these elements and their indices, optimizing both time and space complexity in your solution.

We'll cover the following...

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 ...
