compare

问题 I have some variables in an array. Those may be "Yes", "No", "NA" or "-". For example i have an array arr(1 t0 5) . The values would be 'Yes, Yes, No, No & Yes'. The length of array may vary. Like these the combination may vary given that above four values ("Yes", "No", "NA" or "-") My requirement is that i want to compare the values in array and give a result in a cell of excel work sheet. For example, if all values in array are either 'Yes' or 'NA' then result should be "Yes". If any one

问题 Here is what I wanna do: User can comment up to five times a day (in code I use 60 seconds to see the result quicker). However I seem to make a wrong comparison, because right now it always gives me back true. So even if the counter is above 5, it still counts up instead of stopping there (for 60 seconds). Any input is appreciated. Down below is the code I use. <?php $DB_HostName = ""; $DB_Name = ""; $DB_User = ""; $DB_Pass = ""; $DB_Table = ""; $name = mysql_escape_string($_GET['name']); set

问题 I'd like to know if there's anyway I can compare two BitmapData and get a "similarity percentage" (knowing how look-alike they are). I've done a bit of research and came across bitmapData.compare(otherBmd), but that only returns if they differ in size, or pixel, and not how much they differ. The point of this was to compare some Bmd obtained through a camera with a library image (so this is what I got so far): import flash.display.Bitmap; import flash.display.BitmapData; var img1:BitmapData =

问题 I am tring this method to find the common characters in two strings namely, $a and $r, but the first character isn't getting printed . Moreover the $already collects the common characters and prevents them from being printed for multiple times( I need each character to be printed once only) but it isn't doing so. Please tell me what errors I am making. <?php $a="BNJUBCI CBDIDIBO"; $r="SBKJOJLBOU"; $already=""; for($i=0;$i<strlen($r);$i++) { if (stripos($a,$r[$i])!=FALSE) { if (stripos(

问题 I am trying two compare two strings in JavaScript. But I guess there is some problem while comparing. It doesn't show the results. if(ajaxRequest.readyState == 4){ var msg = ajaxRequest.responseText; var fld = document.getElementById("prtCnt"); if(msg == "false") { var msg = "This User Name is already taken !!!!"; fld.className = "bp_invalid"; // fld.style.color=green; fld.innerHTML=msg; } Can any body tell me where the problem is? Thanks. 回答1: You might want to check if there's any space

问题 I'm studying SQL and can't seem to find an answer to this exercise. Exercise: For all cases where the same reviewer rated the same movie twice and gave it a higher rating the second time, return the reviewer's name and the title of the movie. I don't know how to compare 2 rows and then get the higher rating. The tables' schemas are: Movie ( mID, title, year, director ) English: There is a movie with ID number mID, a title, a release year, and a director. Reviewer ( rID, name ) English: The

问题 I am comparing 2 lists and I need to collect occurrences of a subset (modulesToDelete) from the master list (allModules) ONLY when MORE than one occurrence is found. (allModules contains modulesToDelete). Multiple occurrences of any module in modulesToDelete means those modules are being shared. One occurrence of a module in modulesToDelete means that module is isolated and is safe to delete (it just found itself). I can do this with nested foreach loops but this is as far as I got with a

问题 I will explain this in excel terms just so it will probably be clearer. I have an excel sheet with 2 columns. Column A has 69,000 rows. Column B has 49,000 rows. Column A has our complete product list Column B has product list from Manufacturer 1 There are only certain/some rows which are common between 2 columns. and also, column B is not a subset of column A. Column A has extra entries and so does column B. I need to know, which rows from Column B, are common with Column A which rows from
