Medium data structure and algorithm practice puzzle.
Given a list of scores and a temperature, return softmax probabilities, rounded to 4 decimals. Divide every score by the temperature first, then do a normal softmax: subtract the max, raise e to each, and divide by the total. A low temperature makes the top answer win harder. A high one flattens things out.
Solve it three ways: snap the jigsaw pieces together, fill in the blanks, or type it from scratch against the tests. This one is free.
Every line of the solution comes with a note explaining why it is there, and a step by step replay shows the code running. At level 3, where you type it yourself, you can ask for an AI mock interview on this problem that ends with a hiring manager's scorecard.
Then grow it into a real project with the Software Engineer button: this puzzle becomes the Request Billing Run, a pipeline you can run and download. See every Software Engineer project.
