Which of the following data structures consists of a root node from which all the other elements can be accessed?(1 point)%0D%0AResponses%0D%0A%0D%0Astack%0D%0Astack%0D%0A%0D%0Atree%0D%0Atree%0D%0A%0D%0Amap%0D%0Amap%0D%0A%0D%0Aqueue%0D%0Aqueue
The correct answer is "tree".
The data structure that consists of a root node from which all the other elements can be accessed is a tree.
The data structure that consists of a root node from which all the other elements can be accessed is a tree.
To determine the correct answer, you can examine each option and understand the characteristics of each data structure:
1. Stack: A stack is a linear data structure where elements are added and removed from the top (LIFO - Last In, First Out). It does not have a root node from which all other elements can be accessed.
2. Tree: A tree is a hierarchical data structure that consists of nodes connected by edges. It has a root node that serves as the starting point and is linked to other nodes in a hierarchical manner. All other elements in the tree can be accessed by traversing through the tree starting from the root node, making it the correct answer.
3. Map: A map (or dictionary) is a key-value data structure where each element has a unique key associated with it. It does not have a root node from which all other elements can be accessed.
4. Queue: A queue is a linear data structure where elements are added to the rear and removed from the front (FIFO - First In, First Out). It does not have a root node from which all other elements can be accessed.
Therefore, the correct answer is "tree".
