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...
For example, if we say that an algorithm has a time complexity of O(n), it means that the algorithm’s execution time increases linearly with the size of the input. If the input size doubles, the time it takes to run the algorithm will roughly double as well. If an algorithm is O(...
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 came across a problemhere. I have two submissions here. The first onehereinvolves a queue(deque in Python) that is a BFS approach. The second onehereinvolves a stack that is a DFS approach. So I have a few questions here. What is the time complexity and space complexity of both the...
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. ...
349. Intersection of Two Arrays&&350. Intersection of Two Arrays II 用两个 hash sets(Timecomplexity: O(n)) 对数组排序,用two pointers(Timecomplexity: O(nlogn)): 二叉树(Timecomplexity: O(nlogn)): 用排序法,将hashset换成list即可 :
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 of O(N*Log(N)), this is the reason that generally we prefer to merge sort over quicksort as quick sort does have a worst-case time complexity of O(N*N)...
