can anyone explain me second example?

first monkey should pick coconuts at seconds 3,5,7,9,11,13 and second at 1,4,7,10,13 and that is 11 coconuts.

in the second group, firs monkey should open coconuts at seconds 16,17,18,19,20 second at 17,18,19,20 and third at 18,19,20 and that is 12.

I thought that it should be same number of coconuts.

There is a same number of coconuts, its just that one of the monkeys in the second group wont open up the coconut in the 20th second (because there wont be 3 coconuts but only 2 left).

tnx, i've solved it now

Can you give some hints?

Well, you could check for every amount of coconuts.

I don't think thats fast enough, but I think I figured it out anyway

Well, it isn't, you need to do it faster :P

What is the best strategy for guesing numbers from 1 to 100?

how do you mean guesing numbers?

I think of a number from 1 to 100, and you have to say what number is it.

Binary search?

oh, i didn't realised that you're giving a hint for this task, nice one

;)

Yeah, I figured it out :)
