Medium data structure and algorithm practice puzzle.
Given a list of decimal weights, convert them to integers from -127 to 127. Find the biggest absolute value. That one maps to 127, so the scale is that value / 127. Divide every weight by the scale and round. 8-bit weights take a quarter of the memory of 32-bit ones, which is how big models fit on smaller GPUs.
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 Throughput Report, a pipeline you can run and download. See every Software Engineer project.
