Midpoint Between Two Endpoints | Dataford Interview Questions

Hexagon Ab geometry tools such as HxGN visualization may represent points in 2D, 3D, or higher-dimensional coordinate space. Given two endpoints of a line segment, return the point exactly halfway between them.

Implement midpoint(point_a, point_b) using coordinate-wise averaging. The input points are lists of numeric values with the same positive dimension. For every coordinate i, the result must satisfy result[i] = (point_a[i] + point_b[i]) / 2.

Formal Specification

Input: Two lists point_a and point_b containing integers or floating-point values.
Output: A list of floating-point values representing the midpoint.
The input lists must have equal lengths. Do not mutate either input list.
Floating-point results are considered correct within an absolute error of 1e-9.

Constraints

1 <= len(point_a) = len(point_b) <= 100000
-10^9 <= coordinate <= 10^9
Both points contain finite numeric values
The input points have the same dimension
Neither input list may be mutated

Function Signature

def midpoint(point_a, point_b):
