Typos on map over lists page

[dragoncoder047]

Just noticed some old typos on the map over lists page:

Again, nil represents a gap which is left unchanged. We can use mapcar to invert the whole tune:

> (mapcar inv tun)
(12 12 5 5 3 3 5 nil 7 7 8 8 10 10 12)

or we can play the inverted tune with:

(mapc pla (mapcar inv tun)

…except above, tun has since been renamed to tune and pla to play. (I suspect this code predated long symbols?) Also the second code block is missing the close paren.

Thanks! I’ll fix it.

Still missing a close paren on the second one.

Currently is:

(mapc play (mapcar invert tune)

Should be:

(mapc play (mapcar invert tune))
