Declare double variables x$1,$ y$1,$ x$2,$ and y$2,$ and read each variable from input in that order. Find the midpoint between point $($x$1,$ y$1)$ and point $($x$2,$ y$2)$ and assign the result to xMidpoint and yMidpoint.

The calculation is: midpoint$=($x$1+$x$22,$y$1+$y$22)$

Ex: If the input is $3\mathrm{.}52\mathrm{.}51\mathrm{.}05\mathrm{.}0,$ then the output is:
