print(two_D_vector);//sorting the 2D array based on a particular row//here we sort the last row of the 2D vector//in descending order//so, basically we sort the 1D array in//descending order(the last row)sort(two_D_vector[2].begin(), two_D_vector[2].end(), greater<int>())...
sort_array函数主要用于对数组中的元素进行排序,但它只能对整个数组进行排序,无法针对数组中的特定字段进行排序。 如果你需要对数组中的对象或结构体按照特定字段进行排序,你可以考虑以下几种方法: 使用UDF(用户自定义函数): 你可以编写一个UDF,该UDF接受一个数组作为输入,并根据数组中对象的特定字段进行排序。然后,...
There are two main methods that can be used to sort a 2d array in Python, the sort() function, and the sorted() function.
array_multisort(array_column($array,'key'),SORT_DESC,$array); ?> up down 91 cagret at gmail dot com¶ 15 years ago A more inuitive way of sorting multidimensional arrays using array_msort() in just one line, you don't have to divide the original array into per-column-arrays: <?
array = ["c","b","d","a"] sortIndices(array) [3,1,0,2] array[sortIndices(array)] ["a","b","c","d"] Duplicate values are sorted in the order of appearance. array = [2,1,3,3,1] sortIndices(array) [1,4,0,2,3] array[sortIndices(array)] [1,1,2,3,3] Each row...
