compare

I'm using the sort() function in C++ to sort a vector of objects of type 'Game', which I defined myself. To do this, I am manually writing a function that will act in place of the operator< , and which will be passed as the third parameter to the sort() function. First, I compare based on scores. Then, if scores are tied, I compare based on team name. What I need is a function alphabetical(string s1, string s2) , that will return true if s1 would come before s2 in the dictionary. For example: alphabetical("aardvark", "apple"); //true alphabetical("balloon", "zebra"); //true alphabetical("zebra

I want to compare 2 text files and output the difference in another text file. $Location = "c:\temp\z.txt" compare-object (get-content c:\temp\hostname_old.txt) (get-content c:\temp\hostname_new.txt) | format-list | Out-File $Location hostname_old.txt server02 server05 server04 server06 server01 hostname_new.txt server04 server01 server02 Results InputObject : server05 SideIndicator : <= InputObject : server06 SideIndicator : <= This is what I want : (get rid of both InputObject and SideIndicator) server05 server06 Note: A related problem where one input file has duplicate entries is the

I'm creating a part scanner in C that pulls all possibilities for scanned parts as images in a directory. My code currently fetches all images from that directory and dumps them into a vector. I then produce groups of contours for all the images. The program then falls into a while loop where it constantly grabs images from a webcam, and generates contours for those as well. I have set up a jig for the part to rest on, so orientation and size are not a concern, however I don't want to have to calibrate the machine, so there may be movement between the template images and the part images taken.

Java's PriorityQueue places the least element at the head of the list, however I need it to place the greatest element at the head. What what's the neatest way to get a priority queue that behaves like that. Since I wrote the class stored in this queue I could simply reverse the results of compareTo , its not used outside this queue. However I like to make the code an accurate representation of what I'm modeling, what I'm trying to do is get the greatest first so the code should say that rather than least first with an unusual definition of least. [edit]just a quick thank you everyone,

I'm trying to compare two arrays both 2d, I need it only match when they're completely identical. The code I have is too lengthly, as the arrays will potentially be far longer. I tried playing with .each() and for loops but it get's very messy and won't compare every array. var solution=[ [0,0,0], [0,0,1], [0,0,1]]; var value=[ [0,0,0], [0,0,1], [0,0,1]]; //compare arrays if (solution[0][0]==value[0][0] && solution[0][1]==value[0][1] && solution[0][2]==value[0][2] && solution[1][0]==value[1][0] && solution[1][1]==value[1][1] && solution[1][2]==value[1][2] && solution[2][0]==value[2][0] &&

how do you setup minimum number of comparisons in general? James McNellis To cite Donald Knuth (by way of Wikipedia, since I don't have my copy of TAOCP at the moment), the lower bound for the number of comparisons is six: http://en.wikipedia.org/wiki/Selection_algorithm (scroll down to the section entitled "Lower Bounds"). Your goal is, effectively, to find the k lowest values where k is half the size of the list, rounded up, (so, k = 3; n = 5) and then take the max of those. Plugging that into the formula there on the page, you get: (5 - 3) + 1 + 1 + 2 = 6 In this case, the actual minimum
