I used that same formula to solve the problem too (I was looking the interval of clicks the lamp switched on) and it worked perfect. But reading the contest analisys... i think analisys' solution is more elegant and simply than mine... :)
Well, the problem was solved and that's the important :D 2010/5/9 Abdelrhman Abotaleb <[email protected]> > Ok I'm want really to discuss it > because I solve it using a very simple way. > only single operation!!! :D :D > I deduced a formula relates the number of snappers by the number of clicks > if it satisfy the formula so the lamp is ON ;otherwise the lamp is off > > Indeed this method is sooooooooooooooo efficient for the large data set > input . > > Really in the first I solve it straightforward using recursion algorithms > and so on > > > The formula is ( Number of clicks)+1 divided by (2^(number of snappers) > should be an integer number. > If anyone really interested i may include how to deduce the formula > > Good Luck > > > On Sun, May 9, 2010 at 9:26 AM, Varun Nischal <[email protected]>wrote: > >> Hello all, >> >> Is anyone interested in discussing the algorithm for Snapper Chain. >> What was the right approach to it? >> >> PS: I have seen some solved source code.
