duplicates

问题 I have same problem as Daniel had in this topic, but his solution doesn't work for me: http://www.kendoui.com/forums/ui/grid/kendo-ui-grid-inserts-updates-create-duplicate-records.aspx#-jhxqRrNAUGsTFJaC-Ojwg So use-case. Users adds 2 new records one after another: Presses "Add new record" button of a grid Fills the fields (name="Alex", amount=10, comment="first"). Record one is ready. Press 'Save'. (data goes to controller and than to Database) User see one record in a grid Press "Add new

问题 I have SQL query ; with cte as ( SELECT PARSENAME(REPLACE(replace(replace(replace(replace(dbo.IDENTITY_MAP.Name, 'My Company\', ''), '-VLAN2', ''), '.VLAN2\', ''), '.Instr\', '') , '\' , '.'), 1) as "Site", Count (CASE WHEN dbo.SEM_AGENT.AGENT_VERSION LIKE '11.%' THEN 1 END) AS 'SEP-11', Count (CASE WHEN dbo.SEM_AGENT.AGENT_VERSION LIKE '12.%' THEN 1 END) AS 'SEP-12', FROM dbo.sem_computer INNER JOIN [dbo].[V_SEM_COMPUTER] ON [dbo].[V_SEM_COMPUTER].COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID WHERE

问题 What would be the best means of going about this without explicit comparison? 回答1: If List Of Object contains Strings , You need to Add them to Set . If the list contains Custom object , override equals meth in the custom class and those object to Set 回答2: - Use Collection named Set , which maintains Uniqueness. - Use asList() method of Array to convert it into List , and then use addAll() method to add the List to the Set . - Adding List to the Set will remove the duplicates . Eg: String[]

问题 I have seen some similar answers, but I can't find something specific for this case. I have a list of tuples: [(5, 0), (3, 1), (3, 2), (5, 3), (6, 4)] What I want is to remove tuples from this list only when first element of tuple has occurred previously in the list and the tuple which remains should have the smallest second element. So the output should look like this: [(5, 0), (3, 1), (6, 4)] 回答1: Here's a linear time approach that requires two iterations over your original list. t = [(5, 0

问题 I have a dictionary of unique keys where some keys share the same value. For example: D = {'ida':{'key':'1'},'idb':{'key':'2'},'idc':{'key':'3'},'idd':{'key':'3'},'ide':{'key':'4'},'idf':{'key':'4'},'idg':{'key':'4'}} I want a list of keys that share the same value with other keys. In this case, it would be l = ['idc','idd','ide','idf','idg'] However, I want to exclude one key from all sets of keys that share the same value. For example, I'd like to have the keys l = ['idd','idf','idg'] which

问题 This question already has answers here : Creating random numbers with no duplicates (18 answers) best way to pick a random subset from a collection? (10 answers) Closed 3 years ago . I am trying to get this code to run without duplicates but am having no success researching this area. Its the start of a question I am doing which will ask the user to input the missing element. However, when I generate random elements I am getting duplicates import java.util.Random; public class QuestionOneA2 {

问题 I hope you can help me resolving an issue in VBA with regard to adding a suffix to duplicate values. I have a range that looks like the following: COL A: 000049 000050 000051 000052 (duplicate) 000052 (duplicate) 000053 000054 What I want to achieve is that once there is a duplicate in Column A, it adds a suffix to both numbers. I've only managed (using a loop) to set it for one of the fields. Conditions: If there is a duplicate, all duplicates must have a suffix; If there is a new duplicate

问题 I'm new to C++. I was wondering how I can find duplicate strings in a vector and print out ONE copy of the string. For example, if I had <"cat", "dog", "dog", "bird",> it would print out cat, dog, bird. I have sorted my vector and am using the adjacent_find function and iterating through the vector (since I have to find if any word is duplicated). My code detects duplicates, but it only prints out the non-duplicates. I would like to alter it to print out all the non-duplicates and also just

问题 I'm new in C programming and would love to get some help. I have this struct : typedef struct house { int numOfRooms; char* houseName; }HOUSE,*pHOUSE; I want to create a function that gets a pointer to HOUSE and returns a new pointer to same HOUSE that is located in a different place in memory - the purpose is to be able to change one pointer without changing both : I will try to be clearer : pHOUSE duplicate_house(pHOUSE house) { pHOUSE newh = (pHOUSE)calloc(1,sizeof(HOUSE)); newh = house /

问题 I need to check if in my file there are duplicates entries, in C. Sample file: /proc/proc1 1000 /proc/proc2 2000 /proc/proc1 3000 I need to solve like this: /proc/proc1 1000 3000 /proc/proc2 2000 The path (/proc/proc*) can include spaces likes: /proc/proc hello/foo Here I wrote something to handle /proc/ and their pids, but now I'm stuck on this problem.. 回答1: #include <stdio.h> #include <string.h> int main(void){ char str[]= "/proc/proc hello/foo 4000"; char path[256]; char pid[10]; char *p;
