Use thestd::sortAlgorithm to Sort the String of Characters in C++ In this article, we assume that the sequence of characters is stored in astd::stringobject. Since thestd::stringclass object is iterable, we can
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>())...
