This module provides functions for splitting an amount into coins using given denominations.

The problem of generating change for a given amount, also known as the vending machine change problem (a special case of the knapsack problem), involves finding all possible combinations of coins that add up to a given amount.

"""
This module provides a declarative way to describe delay strategies for controlling the interval between repeated actions, such as retrying a network request.

There are two categories of strategies:

1. Root Strategies: These provide the base logic for calculating delay time.
   - Linear: Increases delay time linearly.
   - Exponential: Increases delay time exponentially.

2. Modifier Strategies: These adjust the delay time calculated by a root strategy.
