Path of Least Resistance

The Challenge

Energy flows through the path of least resistance. For this challenge, you are provided a grid of integers where each integer represents the amount of resistance encountered at a given point on the grid. Energy enters the grid from the left (at any point) and passes through the grid to the right, moving only one column per round.

Programming Challenge

Movement is always to an adjacent row, meaning energy can flow horizontally or

Trend Kata

The trend kata is an exercise in determining the 'trend' of a series of numbers. The algorithm is weighted towards non-zero values and numbers in the series that are changing. A value of zero and numbers in sequence that are the same value, are given less weight in the calculation. The algorithm will be a summing of results, for each pair within the list, shifted by one (1).

This algorithm, will expect a list of numbers... whole numbers and/or decimals.

if the supplied list is empty or does not exist (null), then the trend calculator should return null.
if the list contains only a single value, then the trend calculator should return a value of zero (0).
the resulting trend will always start with a value of zero (0).
the first pair will contain the first two numbers in the list

Vending Machine Kata

In this exercise you will build the brains of a vending machine. It will accept money, make change, maintain inventory, and dispense products. All the things that you might expect a vending machine to accomplish.

The point of this kata to to provide an larger than trivial exercise that can be used to practice TDD. A significant portion of the effort will be in determining what tests should be written and, more importantly, written next.

	Babysitter Kata

	Background
	----------
	This kata simulates a babysitter working and getting paid for one night. The rules are pretty straight forward:

	The babysitter
	- starts no earlier than 5:00PM
	- leaves no later than 4:00AM
	- gets paid $12/hour from start-time to bedtime
