Let’s solve the Dot Product of Two Sparse Vectors problem using the Hash Maps pattern.
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:
nums1.length
nums2.length
...
