Chapter 2.1, Problem 2.11PP
A.
Explanation of Solution
Determining the value of variables “first” and “last” in function “reverse_array”:
From the given question, an array of odd length “cnt = 2k + 1”. Assume k = 0, 1, 2
Case 1:
- When “k = 0”, then “cnt = 2 (0) + 1 = 0 + 1 = 1”.
- Then call the function “reverse_array” with “cnt = 1”.
first | last = cnt - 1 | first < = last | inplace_swap(&a[first], &a[last]) |
first = 0 | last = 1 - 1 = 0 | 0 < = 0 |
inplace_swap(&a[0], &a[0]) Here the both values are equal so value of middle element “a[0]” is “0”. Therefore, “first = 0” and “last = 0”. That is same as the value of “k”. |
Case 2:
- When “k = 1”, then cnt = 2 (1) + 1 = 2 + 1 = 3.
- Then call the function “reverse_array” with “cnt = 3”...
B.
Explanation of Solution
Setting the array element is “0” in the function “inplace_swap”:
- In the “inplace_swap” function, the arguments “x” and “y” point to the same location.
- Once user compute “*x ^ *y”, then the user get the result of “0”. Because of, value of “a ^ a” is “0” for any “a” in the “inplace_swap” function.
- It is based on the property of “^”.
- Calling “inplace_swap” function to the reverse array, the value of middle element becomes “0” for odd array length.
- Once user compute “*x ^ *y”, then the user get the result of “0”. Because of, value of “a ^ a” is “0” for any “a” in the “inplace_swap” function.
Example:
When the array elements are “1, 2, 3, 4 and 5”, then the reverse array is “5, 4, 0, 2, 1”.
- Call the function “reverse_array” with array “a” 1, 2, 3, 4 and 5 and “cnt = 3”.
- Initially array “a” is
a[0] | a[1] | a[2] | a[3] | a[4] |
1 | 2 | 3 | 4 | 5 |
- Steps to find the reverse array...
C.

Modification to the code for “reverse_array” function:
- Replace the test condition of “first <=...

The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period.

To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3.

- Southern Airline has 15 daily flights from Miami to New York. Each flight requires two pilots. Flights that do not have two pilots are canceled (passengers are transferred to other airlines). The average profit per flight is $6000. Because pilots get sick from time to time, the airline is considering a policy of keeping four *reserve pilots on standby to replace sick pilots. Such pilots would introduce an additional cost of $1800 per reserve pilot (whether they fly or not). The pilots on each flight are distinct and the likelihood of any pilot getting sick is independent of the likelihood of any other pilot getting sick. Southern believes that the probability of any given pilot getting sick is 0.15. A) Run a simulation of this situation with at least 1000 iterations and report the following for the present policy (no reserve pilots) and the proposed policy (four reserve pilots): The average daily utilization of the aircraft (percentage of total flights that fly) The…arrow_forwardWhy is JAVA OOP is really difficult to study?arrow_forwardMy daughter is a Girl Scout and it is time for our cookie sales.
