Write a program that uses a while loop to display the following math operations both in the smaller to larger order and then the larger to smaller order with the denominator being $3$ through $99.$ Ensure your application displays the mathematical results.

$1/3\mathrm{.}0+1/5\mathrm{.}0+1/7\mathrm{.}0++1/95\mathrm{.}0+1/97\mathrm{.}0+1/99\mathrm{.}0$

$1/99\mathrm{.}0+1/97\mathrm{.}0+1/95\mathrm{.}0++1/7\mathrm{.}0+1/5\mathrm{.}0+1/3\mathrm{.}0$
