-
|k - n <= L
< k - nL > 0
| n mod 2 = 1
-
So our task is to find max odd n, where k / n > k - n > 0
I wrote the program which solves this set of inequalities but got an error on the test #3. I argued on another:
Let k is max how many it is possible to take, then the second can make so each time by both would be taken k+1
example:
k=5
1-3 2-3
1-5 2-1
And in a result it is necessary to find min k (n mod (k+1)=0)
It is easy
Good luck!!! I have tried to write such prog. But it gives WA#11. |
