Takže moja otázka - je správne nazývať koreň, list, rodičov, deti, súrodencov na strome ako uzly?

odpovede:

Áno. Koreň je „koreňový uzol.„Rodič je„ rodičovský uzol. “List je„ listový uzol “. Strom pozostáva z uzlov. Pojmy root, rodič, dieťa, súrodenec, list atď. Len popisujú vzťahy medzi uzlami.

Napríklad koreňový uzol nemá rodiča. Uzly lístia nemajú deti. Uzly zdieľania zdieľajú rovnakého rodiča.
