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.
To sort in descending order, we need to just change the comparator function. #include <bits/stdc++.h>usingnamespacestd;voidprint(vector<vector<int>>two_D_vector) {for(autoit:two_D_vector) {//it is now an 1D vectorfor(autoij:it) { cout<<ij<<" "; } cout<<endl; } }//to sort...
std::stable_sort: Sort elements preserving order of equivalents. Sorts the elements in the range[first,last) into ascending order, like sort, but stable_sort preserves the relative order of the elements with equivalent values. std::partial_sort:Partially sort elements in range. Rearranges the e...
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 ...
