问题 Somebody made a compare script for me, but it is working like it should be, because I a was little unclear, the code doesn't totally do how I like to have it.

问题 Is there a Linux command-line app which will compare two binary files and exit on the first mis-match? cmp doesn't seem to have the quit opition. 回答1: cmp doesn't have this option , because it always quits on the first mismatch. $ cmp -b /bin/ls /bin/sed /bin/ls /bin/sed differ: byte 25, line 1 is 320 M-P 300 M-@ 回答2: I think you could go by using 3 tools: cmp diff md5sum cmp is better for binary files and diff is better for text files For binary files diff merely reports whether they differ

问题 I have two sorted lists, both in non-decreasing order. For example, I have one sorted linked list with elements [2,3,4,5,6,7...] and the other one with elements [5,6,7,8,9...] . I need to find all common elements in both lists. I know I can use a for loop and a nested loop to iterate all matches to find the same two elements. However, is there another way to do this that has running time less than O(n^2) ? 回答1: You can do it in O(n) time. Pseudocode: a = list1.first b = list2.first repeat: if

问题 I'm definitely a newbie to ruby (and using 1.9.1), so any help is appreciated. Everything I've learned about Ruby has been from using google. I'm trying to compare two arrays of hashes and due to the sizes, it's taking way to long and flirts with running out of memory. Any help would be appreciated. I have a Class (ParseCSV) with multiple methods (initialize, open, compare, strip, output). The way I have it working right now is as follows (and this does pass the tests I've written, just using

问题 I am having two lists List<int> a = {1,2,3}; List<int> b = {3,4}; I need to compare them in such a way that the output should be 1 false 2 false 4 true The output is by using the following logic 1,2 are in a but not in b so they are set to false whereas 3 is in both the lists so its not in the output and '4' is in b but not in a so they are set to true the return type is a List<modelClass> that has int id, bool isTrue properties Can you help me? 回答1: If you don't care about performance you

问题 I have two text files. The first one has a list of words, like the following: File 1.txt Laura Samuel Gerry Peter Maggie The second one has paragraphs on it.

So the desired output should look like this. Laura | MATCH is about to meet Gerry | MATCH and is planning to take
