Use $$for $$loops $$to $$construct $$a $$program $$that $$displays $$a $$pyramid $$of $$

$$

$$s $$on $$the $$screen$.$The $$pyramid $$should $$look $$like $$this

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

$$

except $$that $$it $$should $$be $$

$2$

$0$

$$lines $$high$,$instead $$of $$the $$

$5$

$$lines $$shown $$here$.$One $$way $$to $$do $$this $$is $$to $$nest $$two $$inner $$loops$,$one $$to $$print $$spaces $$and $$one $$to $$print $$

$$

$$inside $$an $$outer $$loop $$that $$steps $$down $$the $$screen $$from $$line $$to $$line$.$
