Match the LIST-I with LIST-II

LIST - I		LIST - II
A.	Breadth First Search	I.	LISP
B.	Depth First Search	II.	Syntax tree
C.	Prefix	III.	Stack
D.	Infix	IV.	Queue

Choose the correct answer from the options given below:

The correct answer is option 4.

Key Points

• Breadth First Search (A) uses a Queue (IV).
  • BFS explores all nodes at the present depth level before moving on to nodes at the next depth level, making use of a queue data structure to keep track of nodes to be explored.
• Depth First Search (B) uses a Stack (III).
  • DFS explores as far as possible along each branch before backtracking, making use of a stack data structure to keep track of the path.
• Prefix (C) is associated with LISP (I).
  • In LISP and other prefix notation systems, operators precede their operands.
• Infix (D) is related to the Syntax tree (II).
  • Infix notation is commonly used in arithmetic expressions and can be represented by a syntax tree where each node represents an operator and its children represent operands.

Additional Information

• Breadth First Search (BFS) and Depth First Search (DFS) are fundamental algorithms used in graph theory and have applications in various fields such as AI, network analysis, and more.
• Prefix notation, also known as Polish notation, and Infix notation are different ways of writing arithmetic expressions used in computer science and mathematics.
• Understanding the differences between these notations and their implementations is crucial for fields like compiler design and expression evaluation.
