Consider the following definition: template Item maximal (Item a, Item b) { if (a > b) return a; else return b; } What restrictions are placed on the Item data type for a program that uses the maximal function?

are there any graphs invested in this equation

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?
