For balanced expression, determine that the expressions should be in appropriate expression and with equal number of opening and closing of brackets in balanced expression.

For example:

((P+Q))+(R+S)) - This is balanced expression

((P+Q)+(R+S}) - This is unbalanced expression

Contrapositive: If water is insufficient, then there isn't healthy plant growth

Increased availability of information is a necessary condition for further technological advances

Contrapositive: Absence of further technological advances implies decreased availability of information.

Errors were introduced only if there was a modification of the program.

Contrapositive: If there wasn't any modification of the program then error was not introduced into the program

Fuel savings implies good insulation or storm windows throughout.

Contrapositive: The absence of good insulation or storm windows throughout implies that there is no fuel savings.

Explanation:

A contrapositive statement is formed from a conditional statement as we can see from the answers above.

In a contrapositive statement, we just interchange the hypothesis and the conclusion of the inverse statement.

This implies that, when the converse of the statement is true, then the inverse of the statement is also logically true.

For each of the following application areas state whether or not the tree data structure appears to be a good fit for use as a s

Cerrena [4.2K]

Answer:

a) Chess game moves:- Tree data structure is not a good fit.

b) Public transportation paths:- Tree data structure is not a good fit.

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit.

d) Genealogical information:- Tree data structure is a good fit.

e) Parts of books:- Tree data structure is a good fit.

f) Programming language history:- Tree data structure is not a good fit.

g) Mathematical expression:- Tree data structure is a good fit.

Explanation:

a) Chess game moves:- Tree data structure is not a good fit. Since in tree data structure moving backward or sharing the node is not that much easy. Presume, In chess, you have to check any box is empty or not. Here, Graph is the best fit.

b) Public transportation paths:- Tree data structure is not a good fit. whenever shortest path, routes, broadcast come always graph is a good option. Because in the tree you don't know how many time you visit that node

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit. Since they have a predefined route. Go to 'c' drive. Open a particular folder and open a particular file.

d) Genealogical information:- Tree data structure is a good fit. Since genealogical information also has a predefined route. Here, the Graph is not suitable.

e) Parts of books:- Tree data structure is a good fit. Since manages the chapters and topics are not that much complex. You can see any book index which is in a very pretty format.

f) Programming language history:- Tree data structure is not a good fit. To store the history of the programming language we need some unconditional jumps that's why the tree is not suitable.

g) Mathematical expression:- Tree data structure is a good fit. The tree is suitable in some cases. We have an expression tree for postfix, prefix.
