I recently was asked to design an algorithm that checks if two strings are anagrams of one another.My goal was to minimize space and time complexity, so I came up with this algorithm:[详细]

How to solve this recurrence: T(n) = T(n/2) + T(n/4) + O(1) It doesn\'t seem like Master Method will help, as this is not in the form of T(n) = aT(n/b) + f(n). And I got stuck for quite 开发者_如何学[详细]

Is there an algorithmic approach to find the minimum of an unsorted array in logarithmic time ( O(logn) )? Or is it only possible in linear time? I don\'t want to go parallel.[详细]

I was always intrigued by Python\'s collections.deque object. It seems to be like a list, except that adding/deleting items in the beginning is faster than in a list.[详细]

I know the following code has a complexity of O(log(n)): while (n>1) { counter++; n/=2; } I understand that here, n is being divided in half on each iteration, meaning that if n was 1000 then it[详细]
