Expert Solution & Answer
Chapter 4, Problem 5RQ
Explanation of Solution
Three building approaches of a lexical analyzer:
The main function of a lexical analyzer is to separate tokens from the input program and to check it syntax validity. The three main approaches to build a lexical analyzer are:
- As lexical analysis involves pattern matching, patterns of the tokens are to be formally described using a language related to regular expression. These formal descriptions for patterns are inputted to an automated software tool which generates a lexical analyzer.
- The second approach is to design a state transition diagram which describes the token patterns...

- Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4.
