Four doubles are read from input, where the first two doubles are the hours and seconds of timeHrSec$1$ and the second two doubles are the hours and seconds of timeHrSec$2.$ Define the function to overload the $+$ operator.

Ex: If the input is $8\mathrm{.}021\mathrm{.}44\mathrm{.}012\mathrm{.}5,$ then the output is:

$8$ hours, $21\mathrm{.}4$ seconds $4$ hours, $12\mathrm{.}5$ seconds Sum: $12$ hours, $33\mathrm{.}9$ seconds

Note: The sum of two time values is:

the sum of the number of hours

the sum of the number of seconds
