At 4:10 what is the word spoken

prateek bhaiya talks about diameter depends on height and then there is a break . can you pls tell what is said in that particular break.

we compute nodes is spoken at 4:10

when we talk about diameter we talk about edges, when we talk about height we talk about nodes.
because in the path A->B->C , nodes are 3 and length of the path is 2
