Time Complexity
hope(n){ if (n == 1) G(n) else F() + hope(n/2); } What is the time complexity for the given function, if the function G' and function F' take O(1) and O(n) unit of time respectively. My views: If we take the recursion in the form of " ... ;log n' times as well? Why can't the answer be O(nlogn) since F() (whose complexity is O(n)) is called 'log n' times?
