int tryMe(int x[], int size); void main() { int list[75]; cout<< tryMe (list, 75); } valid invalid
C++ Consider the following function as a property of a LinkedBag that contains a Doubly Linked List. Assume a Node has pointers prev and next, which can be read and changed with the standard get and set methods. Assume that the doubly linked list is: 1 <--> 2 <--> 3 <--> 4 <--> 5 <-->6 If you are uncertain what the above diagram depicts, it is a doubly linked list such that: The head of this doubly linked list is the node that contains the value 1. The tail of this doubly linked list is the node that contains the value 6. The 3rd node in this list contains the value 3. The contents of this list are the values 1 through 6 in sequential order. The following questions are regarding the linked list after after the test_function is run. A. The head of the list after the test_function is run contains the value: B. The tail of the list after the test_function is run contains the value: C. The 3rd node in the list after the test_function is run…

Language/Type: C++ binary trees pointers recursion Write a function named hasPath that interacts with a tree of BinaryTreeNode structures representing an unordered binary tree. The function accepts three parameters: a pointer to the root of the tree, and two integers start and end, and returns true if a path can be found in the tree from start down to end. In other words, both start and end must be element data values that are found in the tree, and end must be below start, in one of start's subtrees; otherwise the function returns false. If start and end are the same, you are simply checking whether a single node exists in the tree with that data value. If the tree is empty, your function should return false. For example, suppose a BinaryTreeNode pointer named tree points to the root of a tree storing the following elements. The table below shows the results of several various calls to your function: 67 88 52 1 21 16 99 45 Call Result Reason hasPath(tree, 67, 99) true path exists…
