Islands

Problem code: ISLANDS

All Submissions

There is a rectangular N x M grid of square cells. Each cell is either a unit of land or a unit of water. Two cells are adjacent if they share a side. Two adjacent land cells are said to be part of the same island. The size of an island is the number of land cells that form that island.
Given the N X M grid, you are required to find the total number of islands and the size of the largest island.

Input

The first line contains two integers N and M(1<=N,M<=1000), separated by a space. The next N lines contain M characters each. Each of these M characters is either a '.' or a 'x', representing a water cell and a land cell respectively.

Output

The output contains two integers separated by a space. The first integer is the number of islands and the second integer is the size of the largest island.

Example

Input:
4 5
xx..x
xxxx.
..xx.
xx...

Output:
3 8

Explanation:
In the grid below, cells marked with the same number are part of the same island. The island that is marked with the integer 1 has a size of 8.

1 1  .  . 2
1 1 1 1 .

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.
