    <p>I am writing a problem to solve Job schedules but I am having a hard time understanding how.</p> <p>The Wood Shop has a backlog of orders for its world famous rocking chair (1 chair per order). There are several steps involved in making a handmade Baber Rocking chair (eg. cutting wood pieces, assembly, sanding, applying a stain, and applying varnish). </p> <p>The total time required to make a chair is 1 week. However, since the chairs are sold in different regions and various markets, the amount of profit for each order may differ. In addition, there is a deadline associated with each order. The company will only earn a profit if they meet the deadline; otherwise, the profit is 0.</p> <p>Write a program that will determine an optimal schedule for the orders that will maximize profit. The input file will contain one or more test cases. The first line in a test case will contain an integer, n (0 n 1000), that represents the number of orders that are pending. </p> <p>A value of 0 for n indicates the end of the input file. The next n lines contain 3 positive integers each. The first integer, i, is an order number. </p> <p>All order numbers for a given test case are unique. The second integer represents the number of weeks from now until the deadline for i th order. The third integer represents the amount of profit that the company will earn if the deadline is met for the i th order.</p> <p><strong>What I am asking for is an algorithm of how I should go about solving this problem.</strong></p> <p>For each test case in the input file, the output file should output a line that reports the amount of profit that results from completing the orders in an optimal order.</p> <pre><code>Example Input File (sched.in) 7 1 3 40 2 1 35 3 1 30 4 3 25 5 1 20 6 3 15 7 2 10 4 3054 2 30 4099 1 35 3059 2 25 2098 1 40 0 Example Output File (sched.out) 100 70 </code></pre>

    1. COWhat have you done so far? (Nothing that I can see.) It must be the end of the semester - lots of "do my homework for me" questions today. "I am having a hard time understanding how" - I guess that's the point of your class. Try writing some code. Read in the file; write out the file. An Order class. C'mon! Something! Anything.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
