duplicates

I was messing around with the first question here: Reduce duplicate characters to a desired minimum and am looking for more elegant answers than what I came up with. It passes the test but curious to see other solutions. The sample tests are: reduceString('aaaabbbb', 2) 'aabb' reduceString('xaaabbbb', 2) 'xaabb' reduceString('aaaabbbb', 1) 'ab' reduceString('aaxxxaabbbb', 2) 'aaxxaabb' and my solution (that passes these tests): reduceString = function(str, amount) { var count = 0; var result = ''; for (var i = 0; i < str.length; i++) { if (str[i] === str[i+1]) { count++; if (count < amount) {

Is there anyway I can erase all the duplicate entries from a certain table ( users )? Here is a sample of the type of entries I have. I must say the table users consists of 3 fields, ID , user , and pass . mysql_query("DELETE FROM users WHERE ???") or die(mysql_error()); randomtest randomtest randomtest nextfile baby randomtest dog anothertest randomtest baby nextfile dog anothertest randomtest randomtest I want to be able to find the duplicate entries, and then delete all of the duplicates, and leave one . You can solve it with only one query. If your table has the following structure: CREATE

I'm looking for a way to remove duplicate entries from a Python list but with a twist; The final list has to be case sensitive with a preference of uppercase words. For example, between cup and Cup I only need to keep Cup and not cup . Unlike other common solutions which suggest using lower() first, I'd prefer to maintain the string's case here and in particular I'd prefer keeping the one with the uppercase letter over the one which is lowercase.. Again, I am trying to turn this list: [Hello, hello, world, world, poland, Poland] into this: [Hello, world, Poland] How should I do that? Thanks in

If I have query like this, how can I refer to values I have already given in update statement, so that I don't need to insert same data to query again? Example I would like to update col1 value with 'xxx', but now I need to enter 'xxx' again in duplicate statement. Is there anyway to refer those values in duplicate statement? INSERT INTO TABLENAME(col1, col2) VALUES (’xxx’, ‘yyy’) ON DUPLICATE KEY UPDATE col1 = ‘zzz’ Joshua Martell This should work and is a little more elegant: INSERT INTO TABLENAME(col1, col2) VALUES (’xxx’, ‘yyy’) ON DUPLICATE KEY UPDATE col1 = VALUES(col1) Note that you don

I have a simple class representing an object. It has 5 properties (a date, 2 decimals, an integer and a string). I have a collection class, derived from CollectionBase , which is a container class for holding multiple objects from my first class. My question is, I want to remove duplicate objects (e.g. objects that have the same date, same decimals, same integers and same string). Is there a LINQ query I can write to find and remove duplicates? Or find them at the very least? You can remove duplicates using the Distinct operator. There are two overloads - one uses the default equality comparer
