In all questions, you could consider T1(n); g1(n); T2(n)g2(n) are all functions of n. You could consider T1(n) and T2(n) as representing the running time of some algorithm. Assume it is given that T1(n) = O(g1(n)) and T2(n) = O(g2(n)): Prove or disprove each one of the following claims T1(n) + T2(n) = O(g1(n) + g2(n))
