Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.

A company Digicom Parts manufactures 2 types of unique products for laptop and desktop computers. It manufactures 10 types of laptop products and 42 types of desktop products. Each product manufactured by the company has a unique productID from a-z and A-Z. The laptop product have productID (a, i, e, o, u, ALE, O, U) while the rest of the productIDs are assigned to the desktop products. The company manager wishes to find the sales data for the desktop products. Given a list of productIDs of the sales of the last N products, write an algorithm to help the manager find the productIDs of the desktop products.

Professor Gekko has always dreamed of inline skating across North Dakota. He plans to cross the state on highway U.S. 2, which runs from Grand Forks, on the eastern border with Minnesota, to Williston, near the western border with Montana. The professor can carry two liters of water, and he can skate m miles before running out of water. (Because North Dakota is relatively flat, the professor does not have to worry about drinking water at a greater rate on uphill sections than on flat or downhill sections.) The professor will start in Grand Forks with two full liters of water. His official North Dakota state map shows all the places along U.S. 2 at which he can refill his water and the distances between these locations. The professor’s goal is to minimize the number of water stops along his route across the state.

a. Give an efficient algorithm by which he can determine which water stops he should make.

b. Prove that your strategy yields an optimal solution, and give its

Buddys machine shop has a kiosk computer located in the lobby for customers to use. The kiosk computer has recently been updated to Windows 10 from Windows 7 and is not part of a domain. The local computer policy created for Windows 7 has been applied to Windows 10. This policy severely restricts the use of the computer, so that customers can only use the web browser.
Occasionally, an administrator needs to sign in to the kiosk computer to perform maintenance and update software. However, this is awkward because the administrator needs to disable settings in local policy be performing any task. Then, when the tasks are complete, the administrator needs to re-enable the settings in the local policy. Explain how this system can be improved upon.

Write a program that simulates applying a "boost" to a spaceship in a spaceship race game.
A spaceship makes progress by getting a "boost" value between 0 and 10. The boost value
is determined from generating a random number between 0 and 10. Assuming the starting
distance of the spaceship is 0, the program will output the boost value and the total
distance travelled by the spaceship after applying the boost. (Note: Two newlines are output
after the final output of the program).
When a random seed value of 2 is used, the output of the program will look like:
Boost: 6
Distance travelled: 6
