Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

not very easy for newbie as a 7kyu kata if didn't get a clever trick
Oh, I am so careless about the condition, yes, it is a necessary but not enough condition. Thanks! It is really a hard kata
according to kata description:
Note: The minimum of givens required to create a unique (with no multiple solutions) sudoku game is 17.
so the first one should have unique solution, for it has 29 givens (>17), why there are multiple solutions?
original puzzle is valid, and solvable, and > 17 givens, so it should pass the test. maybe the description is somewhere wrong
ruby random test:
puzzle:
[[8, 0, 0, 5, 0, 0, 0, 0, 3], [0, 0, 5, 0, 6, 0, 1, 0, 0], [7, 0, 0, 0, 0, 1, 0, 2, 4], [0, 5, 0, 0, 8, 0, 3, 0, 0], [1, 0, 0, 0, 0, 0, 2, 0, 7], [0, 0, 7, 0, 2, 0, 0, 4, 0], [5, 7, 0, 3, 0, 0, 0, 0, 6], [0, 0, 3, 0, 4, 0, 7, 0, 0], [4, 0, 0, 0, 0, 5, 0, 0, 9]]
my solved:
[[8, 2, 1, 5, 7, 4, 6, 9, 3], [3, 4, 5, 2, 6, 9, 1, 7, 8], [7, 9, 6, 8, 3, 1, 5, 2, 4], [2, 5, 4, 9, 8, 7, 3, 6, 1], [1, 3, 9, 4, 5, 6, 2, 8, 7], [6, 8, 7, 1, 2, 3, 9, 4, 5], [5, 7, 8, 3, 9, 2, 4, 1, 6], [9, 1, 3, 6, 4, 8, 7, 5, 2], [4, 6, 2, 7, 1, 5, 8, 3, 9]]
why Value is not what was expected??? many random test in ruby seems uncorrect.
[[3, 0, 0, 0, 0, 5, 0, 0, 8], [0, 0, 1, 0, 6, 0, 5, 0, 0], [4, 2, 0, 1, 0, 0, 0, 0, 7], [0, 0, 3, 0, 8, 0, 0, 5, 0], [7, 0, 2, 0, 0, 0, 0, 0, 1], [0, 4, 0, 0, 2, 0, 7, 0, 0], [6, 0, 0, 0, 0, 3, 0, 7, 5], [0, 0, 7, 0, 4, 0, 3, 0, 0], [9, 0, 0, 5, 0, 0, 0, 0, 4]]
[[3, 9, 6, 4, 7, 5, 1, 2, 8], [8, 7, 1, 9, 6, 2, 5, 4, 3], [4, 2, 5, 1, 3, 8, 6, 9, 7], [1, 6, 3, 7, 8, 4, 9, 5, 2], [7, 8, 2, 6, 5, 9, 4, 3, 1], [5, 4, 9, 3, 2, 1, 7, 8, 6], [6, 1, 4, 2, 9, 3, 8, 7, 5], [2, 5, 7, 8, 4, 6, 3, 1, 9], [9, 3, 8, 5, 1, 7, 2, 6, 4]]
Value is not what was expected
thanks for notice where i am wrong
should be: 3 - Expected: 3, instead got: 1
error in 1001 in ruby
[40,29,13,21,31,10,49,40,40,4]
for first 40, 40 % [40,29,13,21,31,10,49,40,40,4].size == 0, so 40 is alone in result arr,
but for nex 29, why 29 is alone??? it is not 29 % [29,13,21,31,10,49,40,40,4].size = 29 % 9 = 2,
so [29, 13] is result??? at this moment should get [40,[29,13],21,31,10,49,40,40,4]
it is not a good description for this kata, making so confused
This comment is hidden because it contains spoiler information about the solution
Some test is wrong for ruby
confused description, need explain more clearly
maybe it is not a complete newbie kata for 7kyu, actually, i think it need some skill to do this, should about 5.5 kyu
actually, i can't understand well this kata, so confused
ruby is down
it is a little confused by the description
This should change to 6 or 5 kyu
It should be a 4kyu, not 6kyu data i think
