All tests passed, but not validator 2 - why? You should provide tests for all edge cases, and if tests are passed, validators should be passed too.
Well, validators cannot cover all possible mistakes by users so these things happen.
Set expert mode in options and add this custom validator:
12
8
… … … …
… … … .2.

4. .1. . … …

(I had to add extra spaces cause the forum won’t let me use more than 3 dots in a row)
Expected output:
3 11 6
1 0 0
4 0 7
2 0 6

Nice puzzle, not too difficult
Just wanted to say I found it kind of confusing that the coordinates in the description are written as row-col and not the other way around. Not a big complaint, but it just confused me a little when it said “next position is [5,1]” which made me look in the down left corner and not the up-right.
When you represent a 2-dim array, you tend to display one sub array per line so the sub arrays are naturally considers as the rows of a matrix.
When you give the index of an element you first give the index of the sub array (the “row”), then the index within the sub array (the “column”).
Therefore, in a row/column context, the given order is ALWAYS row, column.
Which is the opposite in a graphical context when you give x then y.
It’s a bit confusing but you get used to it
Hello i have one question .What data is at the input i case 4 ?
If you mean the visible cases, you can click the button (circled in the screenshot below) to see the inputs:
If you mean the validators, it’s better not to share the inputs in public here.
no no I meant real 4 case . I would like to know what`s real data from 4 case.
As long as you’re talking about the cases you can see below the “TEST CASES” tab, you can use the method I mentioned last time to see their details.
P.S. It’s clearer which case you’re talking about if you refer to a case by its number and its name and also use the terms “Test” or “Validator”. It’s not clear what “real case” and “real data” refer to. For this puzzle, we have
- Test 1: Example
- Test 2: Foursome
- Test 3: The Race
- Test 4: Can’t shoot all
- Validator 1
- Validator 2
- Validator 3
- Validator 4
I found my error and fix this thank You for previous ansver
