ParametersDescription arraymandatoryThis is the array that we want to reverse. This function reverses the given array. The program below shows how we can use theSort()andReverse()methods to sort an array in descending order.
{ return a > b; } std::sort(arr, arr + n, compareDesc); // 输出排序结果 std::cout << "Sorted in descending order using custom compare function: "; for (int i = 0; i < n; ++i) { std::cout << arr[i] << " "; } std::cout << ...

It allows us to define how the sort() function will actually perform the search. Sometimes you can get by with the normal version of sort(), but what if we wanted to change how the container was sorted by having it sort by descending order instead of ascending? Or what if we had a ...

Sorting in Descending Order Sorting in descending order is also a common requirement, and theitemgetter()function, along withsorted(), makes it straightforward. Consider a listCwith sublists containing numerical and string elements: fromoperatorimportitemgetter C=[[10,8,"Cat"],[90,2,"Dog"],[...
