问题 I have a 2-d array, containing only 0 or 1. I want to sort it in descend order on rows (no change on each column) using STL sort algorithm. but I don't know how to pass the parameter and how to write the compare function in sort(first, last, comp); like: 0 1 1 1 1 1 0 1 1 0 1 0 would be sorted like this: 1 1 0 1 1 0 1 0 0 1 1 1 my data structure is like this: int **table = 0; table = new int *[row]; for(int i=0;i<row;i++) table[i] = new int[column]; I can only write the sort function like

问题 I have two 2D arrays of integers of the same dimension that I need to compare. I am going to explain what I need with an example where Sjm1 is the "original" array and the Sjm2 array has the same values as Sjm1 but the values of each column are ordered in increasing order (i.e. "0" is the min value of Sjm1 in column 0 so Sjm2[0][0]=0 ; then "70" is the next min value of Sjm1 in column 0 ⇒ Sjm2[1][0]=70 ; and so on). I have a method to sort a "Sjm1" array to "Sjm2". Now I need to build an

Ordering a Django queryset based on other list with ids and scores

旧时模样 提交于 2021-02-10 17:49:54
问题 I'm a bit mentally stuck at something, that seems really simple at first glance. I'm grabbing a list of ids to be selected and scores to sort them based on. My current solution is the following: ids = [1, 2, 3, 4, 5] items = Item.objects.filter(pk__in=ids) Now I need to add a score based ordering somehow so I'll build the following list: scores = [ {'id': 1, 'score': 15}, {'id': 2, 'score': 7}, {'id': 3, 'score': 17}, {'id': 4, 'score': 11}, {'id': 5, 'score': 9}, ] ids = [score['id'] for

问题 I have an assignment I've been working on for a few hours now, and I can't seem to get it quite right. The assignment is to take a random number of names (from stdin), sort them, and then output them in alphabetical order. I can't find any sites online that handle this kind of sorting specifically, and have had no luck trying to implement qsort() into my code. #include <stdio.h> #include <string.h> #include <stdlib.h> int stringcmp(const void *a, const void *b) { const char **ia = (const char

Sorting order items via a hooked function in WooCommerce

…衆ロ難τιáo~ 提交于 2021-02-10 14:42:04
问题 In WooCommerce, I have a product attribute pa_location for "location" with which I sort my order items. When order items have the same location, I'd like to sort them by SKU. So, sort first by location and then by SKU. I looked to "PHP usort sorting multiple fields" but I am unable to figure out how it applies and would work for my function. I have this custom function that works to sort by pa_location , but cannot get it to also sort by _sku . I tried implementing some of the examples in the

问题 I would like to sort the .choice_result divs based on the value of their .score child value. So with my js below, the .choice_result with a .score inside of 100%, should be the first div and not the last. Here's the js: <div class="poll poll_answered"> <div class="poll_div"> <h1><strong>Percentages</strong></h1> <div class="poll_results" style="display: block;"> <div class="choice_result" data-choice_percent="0"> <p class="choice_result_text">First<p> <div class="choice_result_width"> </div>
