4. One can obtain an asymptotically tight bound directly by computing a limit as n goes to infinity. Essentially, if the ratio of functions f(n) and g(n) converges to a positive constant as n goes to infinity, then f(n) = (g(n)). Let fand g be two functions that Lim f(n)/g(n) no exists and is equal to some number c> 0. Then f(n) = (g(n)). Prove the above statement
