Case contract

Daily contest entries are [entry id, score in hundredths]; payouts[r] is the prize in cents for finishing position r (0-based), positions past the list pay 0. Entries with equal scores share the positions they jointly occupy: their prizes are summed and split equally, whole cents only, with leftover cents given one each to the tied entries in ascending id order. Return id -> cents for entries receiving more than 0.

Why this case matters

Tie splitting in paid contests moves real money; cent remainders and the pooled positions must be exact.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
