Soft Threshold Scalar Value

Problem

The scalar soft threshold operator is sign(v) * max(|v| - t, 0).

Given v and t >= 0, return the thresholded value.

Hint

Values within the threshold band collapse to zero.

case 1

in: [1.5,0.5]

expected: 1

case 2

in: [-3,1]

expected: -2

case 3

in: [0.25,0.5]

expected: 0
