0 | |

1 | |

2 | |

3 |

Question 1 Explanation:

In a binary tree, a node can have atmost 2 nodes (i.e.) 0, 1 or 2 left and right child.

Question 2 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER] |

The following given tree is an example for?

Binary tree | |

Binary search tree | |

Fibonacci tree | |

AVL tree |

Question 2 Explanation:

The given tree is an example for binary search since the tree has got two children and the left and right children do not satisfy binary search tree's property.

Question 3 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER] |

A binary tree is a rooted tree but not an ordered tree.

true | |

false |

Question 3 Explanation:

A binary tree is a rooted tree and also an ordered tree (i.e) every node in a binary tree has at most two children.

Question 4 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER] |

1 | |

2 | |

3 | |

Question 4 Explanation:

Three common operations are performed in a binary tree- they are insertion, deletion and traversal.

Question 5 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER] |

What is the traversal strategy used in the binary tree?

depth-first traversal | |

breadth-first traversal | |

random traversal | |

preorder traversal |

Question 5 Explanation:

Breadth first traversal, also known as level order traversal is the traversal strategy used in a binary tree. It involves visiting all the nodes at a given level.
