AND Rounds

Problem code: RESN01

  • All Submissions

All submissions for this problem are available.

Problem statement updated.

You are given a cyclic array A having N numbers. In an AND round, each element of the array A is replaced by the bitwise AND of itself, the previous element, and the next element in the array. All operations take place simultaneously. Can you calculate A after K such AND rounds ?

Input

The first line contains the number of test cases T (T <= 50). There follow 2T lines, 2 per test case. The first line contains two space seperated integers N (3 <= N <= 20000) and K (1 <= K <= 1000000000). The next line contains N space seperated integers Ai (0 <= Ai <= 1000000000), which are the initial values of the elements in array A.

Output

Output T lines, one per test case. For each test case, output a space seperated list of N integers, specifying the contents of array A after K AND rounds.

Example

Input:
2
3 1
1 2 3
5 100
1 11 111 1111 11111
Output:
0 0 0
1 1 1 1 1

According to my understanding

pragrame @ 20 Dec 2009 04:17 PM

According to my understanding of the problem, shouldn't the 2nd output be

"1 1 1 1 1"?

Its BITWISE AND, not LOGICAL

syco @ 20 Dec 2009 04:20 PM

Its BITWISE AND, not LOGICAL AND. In C,C++, etc you can use & operator to perform BITWISE AND.

yeah, but isn't after 100

resnk_DareToCode @ 20 Dec 2009 04:38 PM

yeah, but isn't after 100 rounds bitwise AND of each will result one ?

@admin can u explain the

Blitzkrieg @ 20 Dec 2009 04:43 PM

@admin

can u explain the output of 2nd test  case . According to my understanding  I m getting "1  1  1  1   1 "

The answer should be "1 1 1 1

syco @ 20 Dec 2009 04:44 PM

The answer should be "1 1 1 1 1" for the second test case. Updated

Yeah, looks like the sample

triplem @ 20 Dec 2009 04:44 PM

Yeah, looks like the sample output is wrong.

The answer should be "1 1 1 1

syco @ 20 Dec 2009 04:45 PM

The answer should be "1 1 1 1 1" for the second test case. Updated

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.
