The data are in alphabets.
U, N, I, V, E, R, S, I, T, Y, O, F, P, O, K, H, A, R, A.
Perform pre, in and post order traversals.
I'm confused as how to construct it in the 1st place. Only sense i can apply is assigning numbers to alphabets as A=1, B=2, .... Z=26.
But I got stuck on how to select the root node and also arrange duplicate data.
I would be grateful if you guys construct it for me.
