Re: 11666 Logarithms WA again and agian
Rearranging terms gives us
ln(n)-L = ln(1-x) ; -1 < x < 1

That can be accomplished using binary search on L.
I haven't got AC, though.

Re: 11092 - IIUC HexWorld
To calculate the position of an arbitrary point on this grid, first we have to know on which layer it resides. Example: 0 is on the 0th layer, 3 is 1st, 26 is 3rd, etc. Notice that number of points on each layer is 6^n, the layer can be computed easily. Now that we know the layer, we determine on wh...

Re: why wa 147

Code: Select all
scanf("%d.%d", ¬e, &coin);
