Projection Onto a Box

Problem

The Euclidean projection of a point onto the box [lo, hi] clips each coordinate to the interval.

Given the point and the lower and upper bounds (lo <= hi), return the projected point.

Hint

Clamp each coordinate independently.

case 1

in: [[2,-1,5],0,3]

expected: [2,0,3]

case 2

in: [[0.5,0.5],0.4,0.6]

expected: [0.5,0.5]

case 3

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

expected: [-1,-1]
