Write T(n) and big-O expressions for the following loops. Briefly explain how you calculated T(n). For (int i = 0; i < n; i++) for (int j = 0; j < i * i; j++) cout << j << endl; for (int i = n; i > = 0; i - = 2) cout << i << endl; for (int i = 0; i < n; i++) for (int j = i; j > 0; j/= 2) cout << j << endl;

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?
