Can you explain to me what it means to sort even rows of a square matrix in increasing order and odd ones in declining.And in this code how exactly this can be done #include using namespace std; int main(){ int n=4; int arr [n][n]={ {4,6,2,8}, {5,7,9,15}, {10,3,5,22}, {24,20,18,14} }; cout << "The matrix: \n"; for(int i=0; i arr [i][k]){ temp = arr [i][j]; arr[i][j] = arr[i][k]; arr[i][k] = temp; } } } } } cout<<"\nAfter sorting: \n"; for(int i=0; i
