Recall the formal ADT specification that we studied. Suppose P is defined to be all instances of some type of polygon shape (it doesn't matter what kind), and R is the set of real numbers. Which of the following best reflects the information conveyed by the signature alone in the absence of all other information: P.translate(x,y):RRP None of the other answers accurately reflect the information conveyed by the signature alone. translate is an operation with no preconditions that takes a pair of real numbers as input and returns a new polygon. translate is an operation with no preconditions that takes a pair of real numbers as input and moves a polygon by a specified amount within a coordinate system. translate is an operation with no preconditions that takes a pair of real numbers as input and alters the state of the of a polygon someh. The parameters to translate should be of type Double. Question 11 1 pts Suppose T is the set of all ordered binary trees and G is the set of items that can be stored in the nodes of an ordered binary tree. Which of the foll specification signatures would be the most appropriate for the operation of obtaining the item in the node at which the tree's cursor is currently positioned? Titem():G Titem(G):GG None of the signatures shown are appropriate. t. item() :G Titem():T Titem():G
