counting duplicates in c++

由 大兔子大兔子 提交于 2019-12-01 06:32:21
问题 Let's say I have an array of ints {100, 80, 90, 100, 80, 60} so I want to count those duplicates and save those counter for later. because each duplicate number should be divided by counter like 100 is duplicated 2 times so they should be 50 each. to find duplicates, I used sort. std::sort(array, array + number); for(int i = 0; i < number; i++) { if(array[i] == array[i+1]) counter++; } and I've tried to make counter array to save them on each num of array. but it didn't work. please give me

MySQL Insert row, on duplicate: add suffix and re-insert

由 ◇◆丶佛笑我妖孽 提交于 2019-12-01 06:28:52
My question is rather complex, but I thought I should give it a try. In short, I want to insert a row with a slug (short string with alphas and a dash: this-is-a-slug). The problem is that slug is a unique key and there might be duplicates. When there is a duplicate it should be inserted with a modified slug , like with a suffix: this-is-a-slug-1, if that fails increase the suffix: this-is-a-slug-2. Here's the tricky part, it should be accomplished in MySQL (no PHP involved) and preferably in a INSERT statement (no variables, procedures etc.) I've tried a simple solution like so: INSERT INTO

How to remove duplicate rows from flat file using SSIS?

由 拜拜、爱过 提交于 2019-12-01 05:48:00
Let me first say that being able to take 17 million records from a flat file, pushing to a DB on a remote box and having it take 7 minutes is amazing. SSIS truly is fantastic. But now that I have that data up there, how do I remove duplicates? Better yet, I want to take the flat file, remove the duplicates from the flat file and put them back into another flat file. I am thinking about a: Data Flow Task File source (with an associated file connection) A for loop container A script container that contains some logic to tell if another row exists Thak you, and everyone on this site is incredibly

R - delete consecutive (ONLY) duplicates

由 落爺英雄遲暮 提交于 2019-12-01 03:56:45
问题 I need to eliminate rows from a data frame based on the repetition of values in a given column, but only those that are consecutive. For example, for the following data frame: df = data.frame(x=c(1,1,1,2,2,4,2,2,1)) df$y <- c(10,11,30,12,49,13,12,49,30) df$z <- c(1,2,3,4,5,6,7,8,9) x y z 1 10 1 1 11 2 1 30 3 2 12 4 2 49 5 4 13 6 2 12 7 2 49 8 1 30 9 I would need to eliminate rows with consecutive repeated values in the x column, keep the last repeated row, and maintain the structure of the

Fast sort algorithms for arrays with mostly duplicated elements?

由 安稳与你 提交于 2019-12-01 03:28:44
What are efficient ways to sort arrays that have mostly a small set of duplicated elements? That is, a list like: { 10, 10, 55, 10, 999, 8851243, 10, 55, 55, 55, 10, 999, 8851243, 10 } Assuming that the order of equal elements doesn't matter, what are good worst-case/average-case algorithms? In practice, you can first iterate through the array once and use a hash table the count the number of occurrences of the individual elements (this is O(n) where n = size of the list). Then take all the unique elements and sort them (this is O(k log k) where k = number of unique elements), and then expand

Delete duplicate rows from table with no unique key

由 我的梦境 提交于 2019-12-01 02:58:38
问题 How do I delete duplicates rows in Postgres 9 table, the rows are completely duplicates on every field AND there is no individual field that could be used as a unique key so I cant just GROUP BY columns and use a NOT IN statement. I'm looking for a single SQL statement, not a solution that requires me to create temporary table and insert records into that. I know how to do that but requires more work to fit into my automated process. Table definition: jthinksearch=> \d releases_labels;
