What type of algorithm is this I think the computation can be expressed as (2*3)+((4*2)-(1+5)). is this correct. I know its a postorder tree I just don't know if a left or right subtree exists Print root end. Does it anything to do with recursion or repetition

What type of algorithm is this

This is not an algorithm.

I think the computation can be expressed as (2*3)+((4*2)-(1+5)).

Yes.

I know its a postorder tree

What is a postorder tree? I know what a postorder traversal is, but not sure about a postorder tree.

I just don't know if a left or right subtree exists Print root end.

I can't parse this sentence.

Does it anything to do with recursion or repetition

There is some connection.
