What are the trees data structure ?
--> In the above question we can see some kind of structure . We have some nodes and some branches . The one that are marked with the circle are called as the nodes and those which are marked with the lines are called as the branches . Here we have the nodes and the branches . Hence the tree data structure is said to be created of the nodes and the branches.
Now we have multiple nodes here in the structure . We have the Node A at the top . The node at the top is also called as the root node . The root node does not have any branch incoming . It can have multiple outgoing branches though . The node can also be considered as the super parent . That is the parent of all .
Now understand ahead . We have three outgoing nodes from the node A . This nodes are as follows : B, C and D .
Hence we can say that the B ,C and D are the child nodes of the node or the parent node A . We should always keep in mind that we always trace from the top to the bottom . The one at the top is always the parent and the one receiving the branch is always the child node .
