Dense Passage Dot Score

Problem

Return the dense retrieval score of a query and a passage: their dot product.

The vectors are zipped and are assumed to have equal length, so the shorter one limits the sum.

Hint

A dot product multiplies coordinates pairwise and sums the products.

case 1

in: [[1,2],[3,4]]

expected: 0

case 3

in: [[1,1,1],[1,1,1]]

expected: 3

case 4

in: [[],[]]

case 5

in: [[-1,2],[3,-1]]
