PLAY兄,我仲未答,因為有野問,問清楚先答#F7@3pgjwjH6]

假如啦,我而家面前真係有13粒波子係度,咁在我開始操作前,我知唔知有問題粒係重左定輕左呢? v B0K
~_ q2C2X+}
|U(f
我想清楚而家ge情況係邊種:
(1)你俾13粒波子俾我,話俾我聽有一粒係重左,然後叫我搵出黎
or你俾13粒波子俾我,話俾我聽有一粒係輕左,然後叫我搵出黎%itq6|U
lF/bp
W n'k'}(P
(2)你俾13粒波子我,話俾我聽,唔知佢輕左定重左,叫我搵出黎#q!uG8ooL r
老實說,如果係開如操作前,我已經知佢係輕左or重左(但唔知邊粒係),我知道係一定可以做到的.p`w]Z"X
如果要透過3次操作,要在13粒波子中搵出一粒未知重左定輕左ge波子,我會說是不可能的,MP` ?7\'pFov
但我見到又有人答到wor,雖然我沒有看他們的答案(所以我唔知係邊種情況,我估佢地答0岩掛...)
所以我覺得係問題出在我身上,但又不能確定n+}3HFkrXm

其實playplay係個問題度已經有好大提示,13粒同12粒大同小異,#} }R C.a r)H
可以先諗下12粒點樣solve,
我好耐以前諗過12粒,當時我用我自己嘅方法solve到,
因為得唔得自己可以證實,所以一路冇睇過答案.Vag)l)Jl

亦冇再深入諗個原理,所以亦局限咗自己,
