Note: Assume all required header files are already included in the program

void Revert(int &Num, int Last=2)
{
   Last =(Last%2==0)?Last+l: Last - l;
   for(int C=l; C <= Last; C++)
      Num+=C;
)

void main()
{
    int A=20, B=4;
    Revert(A, B) ;
    cout<<A<<"&"<<B<<end1;
    B--;
    Revert{A,B);
    cout<<A<<"#"<<B<<endl;
    Revert{B);
    cout<<A<<"#"<<B<<endl;
}
