sorting

问题 I have a multivendor Woocommerce shop using Dokan plugin and I'm trying to split out the shopping cart into sections based on who the vendor is. For example: Vendor 1 Product C Product B Vendor 2 Product A Dokan uses a custom role 'vendor' to extend the user class, so to get the ID of the vendors, I should be able to use something like: $post_data = get_post( $cart_item['product_id'] ); $vendor_id = $post_data->post_author; This does work, but it will only get the first vendor ID and simply

问题 I have an assignment in which I must create a list of tuples from a string. I do this by splitting the string with .split(). I then iterate over the list and add the items and the number of repetitions of each item into a dict, like so: for word in s: if word in count_dict: count_dict[word] += 1 else: count_dict[word] = 1 After this I create a list of tuples using: pairs = count_dict.items() Followed by: count_list = [] for pair in pairs: count_list.append(pair) count_list.sort(key=lambda x:

问题 My situation is: I get a 1000*2 matrix and a 1000*1 vector. And the row i in the matrix is mapped to the element i in the vector. And the elements in the vector are all integer. Now I want to sort the elements in the vector from low to high. And I want to get a new matrix with the sequence of the new vector. And the mapping relationships are equal to the original situation. How to do this in Matlab? Thanks! 回答1: Use sortrows: First concat your vector to your matrix: M2 = [V, M]; Then sort

问题 I've looked around and can't seem to find a decent way to solve this issue. I have a column that has rows of names. I'd like to sort each row alphabetically so that I can later identify rows that have the same names just in different orders. The data looks like this: names <- c("John D., Josh C., Karl H.", "John D., Bob S., Tim H.", "Amy A., Art U., Wes T.", "Josh C., John D., Karl H.") var1 <- rnorm(n = length(names), mean = 0, sd = 2) var2 <- rnorm(n = length(names), mean = 20, sd = 5) df <

问题 here is the input i am getting from my flash file process.php?Q2=898&Aa=Grade1&Tim=0%3A0%3A12&Q1=908&Bb=lkj&Q4=jhj&Q3=08&Cc=North%20America&Q0=1 and in php i use this code foreach ($_GET as $field => $label) { $datarray[]=$_GET[$field]; echo "$field :"; echo $_GET[$field];; echo "<br>"; i get this out put Q2 :898 Aa :Grade1 Tim :0:0:12 Q1 :908 Bb :lkj Q4 :jhj Q3 :08 Cc :North America Q0 :1 now my question is how do i sort it alphabaticaly so it should look like this Aa :Grade1 Bb :lkj Cc

问题 I want to build a method in Java for sorting an array according to values in more than a given column. Let me explain that with an example (matrix array): int matrix[][] = { {0,2,432},{1,1,282},{2,2,456},{3,4,191},{4,5,293}, {5,2,475},{6,2,491},{7,5,171},{8,5,134},{9,3,354}}; I need to sort every triplet according to the second position in decreasing order. After that, I need to sort the triplet in increasing order according to the third position. The code that I'm using for that is: import
