概念:sort()函数是C++ STL中的一个排序算法,用于对一个容器中的元素进行排序。 分类:sort()函数属于STL中的算法类别,是一种通用的排序算法,可以用于不同类型的数据结构。 优势:sort()函数具有高效性和通用性,可以对各种类型的容器进行排序,并且在大多数情况下,其性能表现优秀。 应用场景:sort()函数可以应用于各种场景,例如对数组
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>());//print the 2D vectorcout<<"printing the 2D vector after sorting\n";

Map in C++ is an associative container that stores key-value pairs in an ordered sequence of keys. Although we cannot directly have elements sorted with respect to values, there are some indirect ways using which we can sort a Map by values in C++. Method 1: Using std::vector #include ...
intsec; chargroup; }; boolcompBySec(Student a, Student b) { returna.sec<b.sec; } boolcompByGroup(Student a, Student b) { returna.group<b.group; } boolcompByName(Student a, Student b) { returna.name<b.name; } voidprint(conststd::vector<Student>&v) ...
Quicksort has the O(nlogn) average time complexity, which is on par with the merge sort algorithm. Note, though, quicksort algorithm highly depends on the pivot selection method. In this case, we chose the naive version for choosing the pivot value, which was the first element in the vec...
When a large amount of data is to be dealt with, the most efficient way is to store it in an optimized manner, where it is arranged in either ascending or descending format. There are many sorting techniques like Merge Sort, Quick Sort, Bubble Sort, etc. In this article, we will ...
Bubble sort belongs to a quadratic running-time class. In fact, the average time and worst-case performance of this algorithm both are quadratic - O(n2). Thus, this method becomes utterly inefficient for large input data sets. It’s not used practically for this very reason. E.g., if ...
