Dot Product of Two Sparse Vectors
Understand how to implement a SparseVector class to efficiently compute the dot product of two sparse vectors. Explore storing sparse vectors by focusing on nonzero elements to save space, use hash maps for optimal computations, and practice solving this common coding interview problem with hands-on coding exercises and problem-solving strategies.
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:
