Infix Notation We write expression in infix notation, e.g. a - b + c, where operators are used in-between operands. Prefix Notation In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b. PrefixRead more
Infix Notation
We write expression in infix notation, e.g. a - b + c, where operators are used in-between operands.
Prefix Notation
In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b. Prefix notation is also known as Polish Notation.
Postfix Notation
This notation style is known as Reversed Polish Notation. In this notation style, the operator is postfixed to the operands i.e., the operator is written after the operands. For example, ab+. This is equivalent to its infix notation a + b.

Explain the terms infix expression, prefix expression, and postfix expression. Convert the following infix expressions to their postfix equivalents: (a) A – B + C (b) A * B + C / D (c) (A – B ) + C * D / E – C (d) (A * B) + (C / D) – ( D + E)

See lessWrite a top-level program for creating a GRAPH instance and running both Prim’s and Kruskal’s algorithms on it, and printing out the respective MSTs returned, along with the total cost and runtime (in milliseconds) for each one. The input to this top-level program should be an n × n cost matrix for a graph, n being the number of vertices (assume the diagonal elements will always be 0, and elements corresponding to unconnected vertices will be set to −1); this can be read in from a text file. A sample input file is provided at http://web.iitd.ac.in/~sumeet/input_graph.txt, which corresponds to the graph depicted.
