Splunk使用測試報告一、技術組件及原理1. Indexer 將本地或遠程日誌資料做索引。工作機制:可以對具有時間軸的任何格式的日誌資料做索引。這個索引動作是基於時間戳記將資料打亂後放入events中,每個events包含時間戳記、host、source、source type屬性。一般一行日誌就是一個event,如果是xml logs,可能被分解成多個events.當使用者搜尋時,這些events就被splunk搜尋到返回給使用者.Events:A single piece of data
Question:Given a string, determine if it is a palindrome, considering only alphanumeric characters and ignoring cases.For example,"A man, a plan, a canal: Panama" is a palindrome."race a car" is not a palindrome.Note:Have you consider that the
Question:Determine whether an integer is a palindrome. Do this without extra space.Some hints:Could negative integers be palindromes? (ie, -1)If you are thinking of converting the integer to string, note the restriction of using extra space.You
Question:Given a string s, partition s such that every substring of the partition is a palindrome.Return all possible palindrome partitioning of s.For example, given s = "aab",Return [ ["aa","b"], ["a","a","b"] ]Anwser 1 : class
Question :Given a binary tree struct TreeLinkNode { TreeLinkNode *left; TreeLinkNode *right; TreeLinkNode *next; }Populate each next pointer to point to its next right node. If there is no next right node, the next pointer
Question:Follow up for problem "Populating Next Right Pointers in Each Node".What if the given tree could be any binary tree? Would your previous solution still work?Note:You may only use constant extra space.For example,Given the following binary
Question: Given numRows, generate the first numRows of Pascal's triangle.For example, given numRows = 5,Return[ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1]]Anwser 1: class Solution {public: vector<vector<int> >
The use of the jQuery library is growing and growing(just released jQuery 1.4), more and more people are using this useful javascript library. This means that more and more useful jQuery tips, tricks and solutions are coming available. That’s why i
Question:Given an index k, return the kth row of the Pascal's triangle.For example, given k = 3,Return [1,3,3,1].Note:Could you optimize your algorithm to use only O(k) extra space?Anwser 1: class Solution {public: vector<int> getRow(int
Question:Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below.For example, given the following triangle[ [2], [3,4], [6,5,7], [4,1,8,3]]Anwser 1: class Solution
