Alfred wants to plan what to cook in the next days. He can cook various dishes. For each dish the costs of the ingredients and the benefit value is known. If a dish is cooked the second time in a row, the benefit value for the second time is 50 percent of the benefit value of first time, if it is prepared for the third or higher time in a row, the benefit value is 0. For example cooking a dish with benefit value v three times in a row leads to a total benefit value of 1.5*v.
Help him to build the menu which maximizes the benefit value under the constraint that his budget is not exceeded.

Input

The input consists of several test cases. Each test case begins with 3 integers in a line: The number of days k (1 ≤ k ≤ 21) Alfred wants to plan for, the number of dishes n (1 ≤ n ≤ 50) he can cook and his budget m (0 ≤ m ≤ 100). The following n lines describe the dishes Alfred can cook. The i-th line contains two integers: the costs c (1 ≤ c ≤ 50) and the benefit value v (1 ≤ v ≤ 10000) of the i-th dish.
The end of the input is signaled by a test case with k = n = m = 0. You don't need to process this test case.

Output

For each output, print the maximum benefit value reachable with 1 digit after the decimal point. Then print k integers with i-th integer being the number of the dish to cook on day i. Dishes are numbered from 1 to n. Print at least one space or new line character after each integer.
If there are several possible menus reaching the maximum benefit value, select the one with minimum costs, if there are several with minimum costs, you can print any of them.
If every menu exceeds the budget, print only the benefit value of 0.

Example

Input:
2 1 5
3 5
3 5 20
2 5
18 6
1 1
3 3
2 3
0 0 0

Output:

Can someone please explain how you get the answers as in the sample case??

admin 2 @ 26 Jul 2009 07:54 AM

The combination giving the most benefit is if he makes dishes 1 5 and 1 in that order. Even 1,4,1 gives the same benefit, but has a higher cost so 1,5,1 is the answer.

wat about the first test case

wat about the first test case total benifit is 7.5 isnt it......???

HELP

Program should read from standard input and write to standard output. After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. Below are the possible results:

 

  • Accepted Your program ran successfully and gave a correct answer. If there is a score for the problem, this will be displayed in parenthesis next to the checkmark.
  • Time Limit Exceeded Your program was compiled successfully, but it didn't stop before time limit. Try optimizing your approach.
  • Wrong Answer Your program compiled and ran succesfully but the output did not match the expected output.
  • Runtime Error Your code compiled and ran but encountered an error. The most common reasons are using too much memory or dividing by zero. For the specific error codes see the help section.
  • Compilation Error Your code was unable to compile. When you see this icon, click on it for more information.
  • If you are still having problems, see a sample solution here.

CodeChef - A Platform for Aspiring Programmers

CodeChef was created as a platform to help programmers make it big in the world of algorithms, computer programming and programming contests. At CodeChef we work hard to revive the geek in you by hosting a programming contest at the start of the month and another smaller programming challenge in the middle of the month. We also aim to have training sessions and discussions related to algorithms, binary search, technicalities like array size and the likes. Apart from providing a platform for programming competitions, CodeChef also has various algorithm tutorials and forum discussions to help those who are new to the world of computer programming.

Practice Section - A Place to hone your 'Computer Programming Skills'

Try your hand at one of our many practice problems and submit your solution in a language of your choice. Our programming contest judge accepts solutions in over 35+ programming languages. Preparing for coding contests were never this much fun! Receive points, and move up through the CodeChef ranks. Use our practice section to better prepare yourself for the multiple programming challenges that take place through-out the month on CodeChef.

Compete - Monthly Programming Contests and Cook-offs

Here is where you can show off your computer programming skills. Take part in our 10 day long monthly coding contest and the shorter format Cook-off coding contest. Put yourself up for recognition and win great prizes. Our programming contests have prizes worth up to Rs.20,000 and $700lots more CodeChef goodies up for grabs.

Discuss

Are you new to computer programming? Do you need help with algorithms? Then be a part of CodeChef's Forums and interact with all our programmers - they love helping out other programmers and sharing their ideas. Have discussions around binary search, array size, branch-and-bound, Dijkstra's algorithm, Encryption algorithm and more by visiting the CodeChef Forums and Wiki section.

CodeChef Community

As part of our Educational initiative, we give institutes the opportunity to associate with CodeChef in the form of Campus Chapters. Hosting online programming competitions is not the only feature on CodeChef. You can also host a coding contest for your institute on CodeChef, organize an algorithm event and be a guest author on our blog.

Go For Gold

The Go for Gold Initiative was launched about a year after CodeChef was incepted, to help prepare Indian students for the ACM ICPC World Finals competition. In the run up to the ACM ICPC competition, the Go for Gold initiative uses CodeChef as a platform to train students for the ACM ICPC competition via multiple warm up contests. As an added incentive the Go for Gold initiative is also offering over Rs.8 lacs to the Indian team that beats the 29th position at the ACM ICPC world finals. Find out more about the Go for Gold and the ACM ICPC competition here.
