How to solve the given task using BFS algorithm?

Asked 2021-Jun-13 at 22:55

Is there any better or simpler solution for this task:

"A matrix of dimensions MxN is given, filled with the numbers 0 and 1. The field on which the number 0 is written represents land, and the field on which it is written number 1 represents water. Write a function largestLake(int [] [] map) which calculates the size of the largest water surface in the matrix map. The size of a water surface is the number of fields of value 1 that that water surface contains. Two water cells are considered connected if they are adjacent horizontally, vertically or diagonally." ?

Example:
Input:
4 5 //MxN
0 0 1 1 0
1 0 1 1 0
0 1 0 0 0
0 0 0 1 1
Output:
6

I tried to find it with BFS algorithm, but it ended up with too many loops. It says in the task that "The best solution has complexity O (M * N)."

I loaded matrix in main and here is my function:

Sort lines in a text file by value

Asked 2021-Jun-08 at 09:28

I would like to like the WPF application saves time similar to the one in the rankings. Time and number of attempts is not a problem to list but the problem occurs when I want to sort it in a text file. The user will be able to turn on the leaderboard in a text file as well as when the application is completed, the chart (text file) will open and show the user's time.

I'm sure there are much smarter ways of achieving the same result but a very simple way would be to:

Read the contents of the file
Assign the contents to a list
Append your value to the list
Use linq to order the list accordingly
Write the list back to the file

Assuming you want to search (buscar), not to filter.
Search in the selected column, starting in row below selected row. Just traverse the table model until you find the searched value and then select that row. Example for the ActionListener for the button:

As has been stated in the comments, you don't assign a value to all your output signals from the Case statement for each case. As the extract from the language standard can use language that is bit technical and opaque, I will try to write an explanation that is beginner friendly.

You case statement has seven outputs, Z(0..2) and Znot(0..3). Your process is of a type known as combinatorial (i.e. it is not clocked). The standard description of this structure would be to assign all outputs, for all cases. If you look at your first evaluation (when = "000") you can see that you are only assigning values to Z. This implies that you want Znot to retain its previous value, which implies a memory element. A non-clocked memory element is called a Latch.

The reason you get a warning is that Latches violate synchronous design practices. FPGAs are designed to work synchronously. The tools know this, and since in 99% of cases a latch is unintended, will raise a warning. The reason they don't raise an error is that there are some corner cases where a latch is intended, but this is for expert use only.

The correct way to imply a memory element is to use a register. In this case, to imply this would be to drive your process with a clock. If that is not desirable then explicitly state the desired value for every output in every case.

ANSWER

Answered 2021-Apr-17 at 20:12

I found solution. See dbfiddle.

To run window function for distinct values I should get first value from each peer. To complete this I

aggregate IDs of rows for this peer
lag this aggregation by one
Mark rows that are not aggregated yet (this is first row at peer) as _distinct
sum( ) FILTER ( WHERE _distinct ) over ( ... )

Voila. You get sum over DISTINCT values at target PARTITION
which are not implemented yet by PostgreSQL

I made an arithmetic calculator but I want to take it to the next level where the user must enter correct values such as (+, -. *, /) If entering another value must be asked again to enter the correct value.

To do that you can simply put things in a while loop and exit the while loop when required. Also exit is not something that you should be using (Some embeded python implementations does not support exit builtin function). To use exit function you need to import it from module sys. Here is the code put into while loop:
