Data Structure Quiz (Set 20) Data Structures (Set 10) 1 / 10 What is 'graph isomorphism'? A technique used to find the shortest path between two nodes in a graph A technique used to determine whether two graphs are the same A technique used to determine whether two graphs are structurally identical A technique used to find the longest path between two nodes in a graph 2 / 10 What is 'graph coloring'? A technique used to color the nodes of a graph A technique used to color the edges of a graph A technique used to assign colors to the nodes of a graph in such a way that no two adjacent nodes have the same color A technique used to count the number of nodes in a graph 3 / 10 What is 'tree node'? A node with multiple parents in a tree A node with multiple children in a tree A node with no parent in a tree A single element in a tree data structure, which can have children nodes 4 / 10 What is 'depth-first search (DFS)'? A search algorithm that explores as far as possible along one branch before backtracking A search algorithm used to find the shortest path between two nodes in a weighted graph A graph traversal algorithm that visits all nodes at a particular level before moving to the next level A search algorithm used to find the longest path between two nodes in a graph 5 / 10 What is 'breadth-first search (BFS)'? A search algorithm used to find the shortest path between two nodes in a weighted graph A search algorithm that explores as far as possible along one branch before backtracking A graph traversal algorithm that visits all nodes at a particular level before moving to the next level A search algorithm used to find the longest path between two nodes in a graph 6 / 10 What is the 'minimum spanning tree' of a graph? A tree that includes the longest path in the graph A tree where all nodes have the same height A tree that includes all nodes of the original graph and a subset of its edges, forming a connected subgraph A tree that has the same number of nodes in both the left and right subtrees 7 / 10 What is 'graph traversal'? The process of traversing a tree data structure The process of visiting and exploring all nodes and edges in a graph The process of sorting elements in a graph The process of deleting nodes from a graph 8 / 10 What is 'sparse matrix'? A matrix with many non-zero elements A matrix with few non-zero elements A matrix with only diagonal elements A matrix with elements that are all zero 9 / 10 What is 'hash function'? A function that converts strings to numbers A function used to search for elements in an array A function used to calculate the sum of elements in a data structure A function that maps keys to hash values, which are used to index data in hash tables 10 / 10 What is 'avl tree'? A binary search tree with the same number of nodes in both the left and right subtrees A binary search tree where the heights of the left and right subtrees of any node differ by at most one A self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one A binary search tree that has more nodes in the left subtree than the right subtree Your score isThe average score is 0% 0% Restart quiz
