Function find_best_split_size 

pub fn find_best_split_size(
    total_items: usize,
    min_size: usize,
    max_size: usize,
) -> usize

Find the best split size for dividing a total number of items given a range of sizes.

Searches from starting with min to max to ideally find an even split with no remainders. Otherwise, choose a size that minimizes the remainder favoring smaller sizes.

Arguments

• total_items - Total number of items to split
• min_size - Minimum size per split
• max_size - Maximum size per split

Returns

The optimal partition size
