std::cout $<<$ "Original: $"<<$ input $<<$ std::endl;

std::cout $<<$ "Reversed: $"<<$ reversed $<<$ std::endl;

return $0$;

$\}$

The code above has a function that that outputs:

Original: Do or do not, there is no try

Reversed: try no is there not, do or Do

I want the reversed portion of the output to have a comma between the words "there" and "not" so that the output can look like this instead:

Original: Do or do not, there is no try

Reversed: try no is there, not do or Do

How can I edit my code so that the comma can be placed in the intended position?
