An automated packaging system is responsible for packing boxes. A box is certified to hold a certain weight. Given an integer total, calculate the number of possible ways to achieve total as a sum of the weights of items weighing integer weights from 1 to k, inclusive. Example
total= 8
k=2

explanation:

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
