Turn up the temperature

One dial decides whether a model plays it safe or takes a chance.

Temperature changes how sure a model sounds. Divide every score by the temperature t, then run softmax. A small t sharpens the odds toward the top score; a big t flattens them out.

Write withTemperature(scores, t): scores is an array of numbers and t is a positive number. Return the probabilities as an array the same length as scores, adding up to 1.

Call show(probs) with your answer and the stage draws it as bars.

Example: withTemperature([0, 0], 2) returns [0.5, 0.5].
