[Community Puzzle] Crop-Circles

Jelad · April 6, 2023, 1:43pm

I think something is incoherent.
For example in the HalfMoon test, the ‘j’ column should always show crop since it is right in the middle on the 2 circles.
The two centers are at same distance from this column.
So either the ‘jm’ point (for exemple) is touched by both circles, either it is touched by none.
In all case, the crop should appear.

However, the expected result is no crop for ‘jk’,‘jl’,‘jm’,‘jn’,‘jo’.
Since the instructions are sequential (I guess) this is inconsistant ; behavior is not the same for circle 1 and 2.

Hi Jelad –

Thanks for playing my puzzle.

This is Not one where a crop appears. This is all DESTRUCTIVE of the crops. I suggest you re-read the puzzle.

A spot may be destroyed twice; that is the same thing as being destroyed (aka mowed) once, or ten times.

Does that address your concern? If not, please post again.

Ok it works fine now ; I miss read a part of the instruction ; I tough the default action was reverse.
Thank you

What kind of geometry were you learning in 4th grade?

I liked the puzzle, but it took me a while to figure out which was the way to actually make a circle. I think the definition of circle should be more explicit in the problem text because it is not intuitive, even if it’s, I reckon, geometrically understandable.

For example, using Pitagora’s theorem to define the circle as every point with (distance <= diameter/2) from the center, in the case of a circle with diameter 3 and center ff you get as output this(a square):

Which in my opinion, is not close to a good circle definition.

Hello, I’d like some help. I’m stuck at the first test :

{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}
{}{}{}{}{}{}{}{}{}{}{}{}{}{}  {}{}{}{}

{}{}{}{}{}{}{}{}{}{}{}  {}{}{}{}{}{}{}
{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}{}```

If I understand correctly what I'm supposed to see, I'm missing a few points near the corners. 

My code looks like that :

> for i in range(radius+1):
>         for j in range(radius+1):
>             if i**2 + j**2 <= radius**2:
>                 min_line = max(0, center_line-i)
>                 max_line = min(24, center_line+i)
>                 min_col = max(0, center_col-j)
>                 max_col = min(18, center_col+j)
>                 edit_field(min_line, min_col)
>                 edit_field(min_line, max_col)
>                 edit_field(max_line, min_col)
>                 edit_field(max_line, max_col)

where field is defined like this : 
field = [["{}"]*19]*25

and edit_field is defined like this: 

> def edit_field(y, x):
>     line = field[y][:]
>     line[x] = "  "
>     field[y] = line[:]

I'd really appreciate a clue. Thank you

The radius appears to be incorrect. You might have used integer division instead of floating-point division when calculating the radius from the diameter.

Hello, I’d like a little extra help here (thanks again for the first answer). I’m stuck on test 4 Bull’s eye (and also on test 5). Here’s what I get with my program:

action = MOW, col = 9, line = 12, diameter = 31
action = PLANTMOW, col = 9, line = 12, diameter = 27
action = PLANTMOW, col = 9, line = 12, diameter = 23
action = PLANTMOW, col = 9, line = 12, diameter = 19
action = PLANTMOW, col = 9, line = 12, diameter = 15
action = PLANTMOW, col = 9, line = 12, diameter = 11
action = PLANTMOW, col = 9, line = 12, diameter = 7
action = PLANTMOW, col = 9, line = 12, diameter = 1

Your program parses the instructions correctly. However, the output is a bit difficult to read. Could you format the output as preformatted text?

When trying to edit a spot that is out of range (e.g. when center_line-i, center_col-j is -1, 1), your code edits some other spot on the field boundary (in this case 0, 1) instead of skipping this spot.

This puzzle is very interesting.
But something a little bit strange happens to me.
The Bulls eye and Bonus test failed. But when I submitted my code it pass every test.
There might be some minimal bug.

This is my output

Standard Output Stream:

And this is the correct output:

    {}{}{}{}              {}{}{}{}    
      {}{}{}{}{}{}{}{}{}{}{}{}{}

I think the only difference are the curly braces just in the middle of the graph

5DN1L · August 5, 2024, 8:40am

How does that middle spot (row 12, column 9) change when you follow the instructions one by one? Here’s mine for your comparison:

jm31: removed crop
PLANTMOWjm27: planted crop
PLANTMOWjm23: removed crop
PLANTMOWjm19: planted crop
PLANTMOWjm15: removed crop
PLANTMOWjm11: planted crop
PLANTMOWjm7: removed crop
PLANTMOWjm1: planted crop

Hence, the final result is that a crop {} is planted at that spot.

Wishmaster-89 · August 6, 2024, 11:10am

Thanks. I had checked it again. It was just a simple misstype of a single space in the mid cell instead of doble space

BerserkVl · October 30, 2024, 11:57am

I spent more time on the task than it actually takes because when I was studying, elementary school was called grades 1 through 4 and there was only basic mathematics (and geometry was covered in senior grades 5+), so I thought it was a trick(Do not use them; stick with what you learned in elementary school.) and started looking for algorithms that are used to draw raster circles and all of them turned out to be unsuitable for this task, and only the next day I realized that the solution is very simple and yet this was a hint, not a trick.

Thank you for the puzzle!
