Extract specific line from text script

由 微笑、不失礼 提交于 2019-12-12 02:36:24
问题 I am trying to get a script working to extract a specific line out of multiple text files at once. I have the script that will extract the line out of the text but I cannot get it to do this to multiple files. What I have is an inventory file for each computer at my facility. I'm trying to extract like 16 which has the user's name so each file will have a different value on line 16 but it's always line 16. Example file I'm trying to extract from: <HTML> <BODY> <center> <table border=1> <tr>

How can i get union of 2D list items when there occurs any intersection (in efficient way)?

问题 I have 2D list in python list = [[9, 2, 7], [9, 7], [2, 7], [1, 0], [0, 5, 4]] I would like to get union of list items if there occurs any intersection. For example [9, 2, 7] , [9, 7] , [2, 7] has intersection of more than one digit. The union of this would be [9,2,7] . How can i get the final list as follows in efficient way ? finalList = [[9,2,7], [0, 1, 5, 4]] N.B. order of numbers is not important. 回答1: You have a graph problem. You want to build connected components in a graph whose

What is an alternative set-like data structure when modifying elements is necessary?

由 百般思念 提交于 2019-12-12 02:15:47
问题 STL sets are designed so that it is not possible to modify the elements in the set (with good reason, see stackoverflow). Suppose however I have a structure in which only one of the members acts as the key. Is there an alternative data structure to a set. I really want exactly the behavior of sets except this inability to modify a field or member which is non-key. 回答1: May be it's time to redesign, considering std::map instead of std::set. instead of struct A { K key; V val; }; set<A> a;

Can we conclude a set might not be random by checking its subset?

由 為{幸葍}努か 提交于 2019-12-12 01:37:48
问题 Set A includes 1000 numbers. I checked that half of the numbers in this set are even. I extracted subset B from set A as follow: any number in set A which starts with 1 is also in set B. (All numbers in B start with 1). I checked that more than half of the numbers in set B are even. Half of the numbers in A are even so should we expect the same for B? But more than half of B are even. So can conclude that set A is not random? If 60% of B are even, can we still conclude A is not generated

Number of Groups Consisting of 3 Decreasing values in Integer Array (Below O(n^3) Time) [duplicate]

问题 This question already has answers here : How to find 3 numbers in increasing order and increasing indices in an array in linear time (13 answers) is it possible to find all the triplets in the given array for the O (n) time? (1 answer) Closed 3 years ago . A decreasing triple is defined as a set of 3 values {a, b, c} that decrease in magnitude from left to right such that a > b > c. How could one find the number of these triples in an array of integers where the indices of the triple {i, j, k

How to fix my Pthreads code about Mandelbrot set?

由 [亡魂溺海] 提交于 2019-12-12 00:55:27
问题 I have the following Pthreads code about calculating and creating a picture of the Mandelbrot set. My code in C works just fine and it prints the resulting picture nicely. The point is that using the below code, I am able to compile the code and execute it. Afterwards, if I try to view the resulting .ppm file in Gimp, it simply cannot open it. I guess I'm doing something wrong in my code. If someone could help me I would be glad. // mandpthread.c // to compile: gcc mandpthread.c -o

Visual Studio Assertion Failed on C++ set comparator

由 我们两清 提交于 2019-12-11 23:59:52
问题 my code are having some problems on my Visual Studio 2010 but not on DevCPP. Heres the situation, I used C++ STL set in my code to insert pair<string, double> but then I want my set to sort them using the value instead of the key, so I used a custom comparator to achieve this. struct sortPairSecond { bool operator()(const pair<string, double> &lhs, const pair<string, double> &rhs) { return lhs.second >= rhs.second; } }; The code works fine in DevCPP but encountered the Debug Assertion Failed
