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.?
ASimple Solutionis to run two nested loops. The outer loop picks all elements one by one and inner loop counts number of occurrences of the element picked by outer loop. Time complexity of this solution is O(n2). ABetter Solution is to use Hashing. Use array elements as key and their ...
Use a TreeMap tm to stroe mappings between interval start and index i. For each interval, find ceiling key on interval's end. That would be the first right interval. Time Complexity: O(nlogn). n = intervals.length. Space: O(n). ...
Time Complexity: O(nlogn). n=hs.size(). 就是所有点的个数. 得到hs用了O(n). forest union用了 O(nlogn). 得到resHashMap用了O(nlogn). 得到res用了O(nlogn). Space: O(n). AC Java: 1/**2* Definition for Directed graph.3* class DirectedGraphNode {4* int label;5* ArrayList<Dire...
time complexity O(n log n) instance.collectFaces(skipTriangulation) params skipTriangulation {Boolean} (default: false) True to skip the triangulation and return n-vertices faces returns An array of 3-element arrays (or n-element arrays if skipTriangulation = true) which are the faces of the...
2.1. What Is Cyclomatic Complexity? Code complexity is important, yet difficult metric to measure. PMD offers a solid set of rules under its Code Size Rules section, these rules are designed to detect violation regarding methods size and structure complexity. CheckStyle is known for its ability ...
