More efficient sampling: The original code (UK National Lottery Predictor4) used a loop to generate combinations until one without duplicates was found. This could be inefficient for large datasets. The new code uses a more efficient sampling method from the probability distribution, avoiding the need for a loop.

Dynamic ball range: The original code assumed a fixed ball range of 1:59. The new code makes the ball range dynamic based on the number of balls in the lottery, ensuring the predictions are accurate for different lottery formats.

Separate prediction function: The original code had the prediction logic embedded within the main script. The new code extracts the prediction logic into a separate function, making the code more modular and reusable.

Vectorised prediction: The original code predicted combinations one by one. The new code uses vectorisation to predict all combinations in a single loop, improving performance.

Clearer output format: The original code printed the predictions within a loop. The new code uses a more structured format with a header and labelled sets, making the output easier to read.
