## Build Parse Tree from expression

I'm sorry if this is the wrong forum, I'm unsure as to where to put it.

I'm trying to build a parse tree from the following expression:-

¬a & ¬(b & ¬c)

I have the tree below, just wanted to check I've got the right idea.

&
/ \
¬ ¬
| |
a &
/ \
b ¬
|
c

Thanks,
