Six doubles are read from input as variables distance$1$ to distance$6.$ Declare a vector of $12$ doubles named swimmingDistance. Initialize the elements at the even indices with the value $0$ and the odd indices with the variables distance$1$ to distance$6$ in the order the input doubles are read.

Ex: If the input is $18\mathrm{.}188\mathrm{.}6211\mathrm{.}3318\mathrm{.}0222\mathrm{.}19\mathrm{.}9,$ then the output is:

$018\mathrm{.}1808\mathrm{.}62011\mathrm{.}33018\mathrm{.}02022\mathrm{.}109\mathrm{.}9$

Note: Index $0$ is considered an even index.
