let f(n)= ( (n^2+2n)/n + 1/1000*(n^(3/2)))*log(n) the time complexity function both o(n²*log(n)) , o(n^(3/2)*log(n)) how possible? thought dominating term here n² (*log(n)) , therefore should o(n²*log(n)) big o notation , time complexity measures feels ambiguous big o notation isn't confusing. defines upper bound running time of algorithm, hence, if o(f(n)) valid upper bound, every other o(g(n)) such g(n) > f(n) definitively valid, since if code run in less f(n) , sure run in less g(n) . in case, since o(n^2 *log(n)) dominates o(n^(3/2) log(n)) , it's valid upper bound too, if it's less strict. furthermore, algorithm o(n^3) . question is, 1 of big o notation gives more informations algorithm? obvious answer lower one, , that's reason why indicate that. to make things cler : let's can throw ball in air 10m. then, can can't throw higher 10m, or can't throw higher 15 meters. fact first 1 stricter upper bound, doesn't make se...
