To maximize proficiency, NameNode stores the complete metadata of HDFS in the core memory. With too several small files, NameNode can be run out of memory. In this paper, we present a solution used by numerous NameNode. Our explanation has topmost returns than existing one: we implement a...
Types of Time Complexity How to calculate time complexity? Time Complexity of popular algorithms Conclusion Watch this Time and Space Complexity of Algorithms from Intellipaat. What is Time Complexity? Time complexity is a measure of how fast a computer algorithm (a set of instructions) runs, depe...
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...
I thought my solution worked in O(n) but it clearly either doesn't or something else is very wrong. My thought process was that both makeWanted and dfs should work in O(n) since there are no loops in a tree, so solve() should be O(n) as well. I'd be incredibly thankful if y...
It does look like the BFS and DFS approach have the same time complexity and space complexity but if I have got that wrong, how do I know when to use DFS and when to use BFS particularly the grid questions involving number of components?(The editorial suggests any of DFS or BFS so sti...
The time complexity of slowSort is O(n2), where nis the number of pairs in the map. Your task is to implement a method called fastSort which performs the same task as slowSort but with a time complexity of O(n·log(n)). [68 points] The SearchEngine class has the following fields...

How to calculate “hard” runtime complexity? 在技术面试中,准确说出一个解法的runtime complexity(算法时间复杂度)是一个非常重要的点。考虑到对于算法时间复杂度的理解是CS领域的基础,因此这类问题,回答对了往往那不加分,但是回答错误往往是致命的,因此大家不能掉以轻心。
Merge Sort Algorithm is considered as one of the best sorting algorithms having a worst case and best case time complexity ofO(N*Log(N)), this is the reason that generally we prefer tomerge sortover quicksort as quick sort does have a worst-case time complexity ofO(N*N). ...
Bubble sort's time complexity in both of the cases (average and worst-case) is quite high. For large amounts of data, the use of Bubble sort is not recommended.The basic logic behind this algorithm is that the computer selects the first element and performs swapping by the adjacent ...
