Distance Between Two Points
Return the straight-line (Euclidean) distance between two points. The points have the same number of coordinates, which may be 2 (a plane), 3 (space) or any other dimension.
distance([0, 0], [3, 4]) -> 5 distance([1, 2, 2], [0, 0, 0]) -> 3
Results are compared as numbers, so return the exact floating-point distance.
Hints
Hint 1
In 2-D it's the Pythagorean theorem: sqrt(dx² + dy²). In 3-D add dz². The pattern doesn't stop at three.
Hint 2
Zip the coordinates, sum the squared differences, take one square root — the same line works for any dimension.
