问题 I am getting the right result for the awk program below. But I dont understand how does AWK process lines of code for the below program : { for(i = 1; i <= NF; i++) { if (min[i]==""){ print "initial min " $i; min[i]=$i;} #line1 if (max[i]==""){ print "initial max " $i; max[i]=$i;} #line2 if ($i<min[i]) { print "New min " $i; min[i]=$i;} #line3 if ($i>max[i]) { print "New max " $i; max[i]=$i;} #line4 } } END { OFS="\t"; print "min","max"; for(i = 1; i <= NF; i++) { print min[i],max[i]; } }

问题 When you search something in Stackoverflow it cuts the portion of the question description that best matches your criteria and after that it marks the criteria words. I wonder the best way to do this manually in C#, meaning without the help of a full-text search engine. The main problem is how to select the best text portion in a fast way? What I did so far is: I obtain the space indexes of the text. This allows me to know where the words begin so that I can start my substring tests from them

问题 I am trying to split a word into bi-grams. I am using the qlcMatrix package, but it only returns distinct bi-grams. For example, for the word "detected" , it only returns "te" once. This is the command I use test_domain <- c("detected") library("qlcMatrix", lib.loc="~/R/win-library/3.2") bigram1 <- splitStrings(test_domain, sep = "", bigrams = TRUE, left.boundary = "", right.boundary = "")$bigrams and this is the result I get: bigram1 # [1] "ec" "ed" "de" "te" "ct" "et" 回答1: Another way to do

问题 Suppose we are doing a multiline regex pattern search on a bunch of files and we want to extract the matches from grep. By default, grep outputs matches separated by newlines, but since we are doing multiline patterns this creates the inconvenience that we cannot easily extract the individual matches. Example grep -rzPIho '}\n\n\w\w\b' | od -a Depending on the files in your filetree, this may yield an output like 0000000 } nl nl m y nl } nl nl i f nl } nl nl m 0000020 y nl } nl nl m y nl } nl

问题 This question is a generalized version of the Output of ZipArchive() in tree format question. Just before I am wasting time on writing this (*nix command line) utility, it will be a good idea to find out if someone already wrote it. I would like a utility that will get as its' standard input a list such as the one returned by find(1) and will output something similar to the one by tree(1) E.g.: Input: /fruit/apple/green /fruit/apple/red /fruit/apple/yellow /fruit/banana/green /fruit/banana

问题 Consider the following file var1 var2 variable3 1 2 3 11 22 33 I would like to load the numbers into a matrix, and the column titles into a variable that would be equivalent to: variable_names = char('var1', 'var2', 'variable3'); I don't mind to split the names and the numbers in two files, however preparing matlab code files and eval'ing them is not an option. Note that there can be an arbitrary number of variables (columns) 回答1: I suggest importdata for operations like this: d = importdata(

问题 I have a nested dictionary as such: myDict = {'a': {1:2, 2:163, 3:12, 4:67, 5:84}, 'about': {1:27, 2:45, 3:21, 4:10, 5:15}, 'apple': {1:0, 2: 5, 3:0, 4:10, 5:0}, 'anticipate': {1:1, 2:5, 3:0, 4:8, 5:7}, 'an': {1:3, 2:15, 3:1, 4:312, 5:100}} The outer key is a word, the inner keys are file/document ids the values are the number of times the word (outer key occurs) How do I calculate the sum of the square values to the inner keys? For example for the inner key number 1 , I should get: 2^2 + 27

问题 What I need is a batch file that reads partial file names in a txt file. Each file name is on its own line. Then it needs to search for that file in a specified folder (including sub folders) and if the file is found, copy the file to a folder on my desktop. I found a batch script that does almost exactly that, but my file names aren't a complete file name, only part of it with no extension, and this script searches for exact file names. I need to modify this script to search for files using
