Finding out the time complexity of your code can help you develop better programs that run faster. Some functions are easy to analyze, but when you have loops, and recursion might get a little trickier when you have recursion. After reading this post, you are able to derive the time comple...
why I want to know the time complexity(with explanation). My logic was to store all the K pairs in a map<int , vector> such that the first element of each pair acts as key , its value being a vector of all the values the key is making a pair with. Now I iterate from 1 till...
Find the time complexity in O-notation for the following recurrence relations using Master method. T(n) = 2*T(n/2) + n*log(n) I tried to solve it using master method but it doesn't seem to fit any of the three cases. Am I correct.?

The time complexity of binary search distanceansisO(max(ai))O(max(ai)). Then we need to find out a method to judge whetheransis the Kth distance, the method is like two pointers, the cost time of this step isO(n)O(n). You can see the code below. ...

A motherboard, like a backplane, provides the electrical connections by which the other components of the system communicate, but unlike a backplane also contains the central processing unit and other subsystems such as real time clock, and some peripheral interfaces. A typical desktop computer is...
