[size=5][color=Teal]在推理問題時,我們可以用 '' 如果/ if ''

在 ''如果'' 之下有''如果'' .....一直至沒有''如果'' .....那就是真正答案p7m7q/\!j Wt4P

但推理問題時,我們用 ''假設''
1Q/j Z#\6CL1H
那就會一直''假設''下去 , 但所得出來的答案 , 既不能證明''假設'' 之本身是否正確 ,它亦只是一個''假設'' 的答案 , if ''假設'' 有誤 , 那麼''錯誤''又豈能得出''正確''[/color][/size]

PLAY兄,我仲未答,因為有野問,問清楚先答
[color=White]
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?
&H_,d+w0}B5_ g(|
我想清楚而家ge情況係邊種:&y2gSO5tX/ge
(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DrZuQeE*lp
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

(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y*y6^8qE F'X6YK

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d/R)La_$Er+Ap
如果要透過3次操作,要在13粒波子中搵出一粒未知重左定輕左ge波子,我會說是不可能的8?.R|/uG] sr$[ Oq
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

唔知佢輕左定重左!!! 如果知輕重,還須要諗嗎?$uTm@r

sakura兄,如果凡事一開始就存否定態度,
而不嘗試探索一下,會自己局限了自己世界觀.

試一試再想想才去否定還未遲.0K[*kAwS7C+Q

不過原來playplay個答案係好簡單,
我鑽牛角尖了,我真蠢:cry:

情況(2),唔佢知輕左定重左.%\'Q_ Ji-P7db _:o

其實playplay係個問題度已經有好大提示,13粒同12粒大同小異,zS7zxCbD6~
可以先諗下12粒點樣solve,oSts4hJ
我好耐以前諗過12粒,當時我用我自己嘅方法solve到, _^:V,H)v7g)E
因為得唔得自己可以證實,所以一路冇睇過答案.Vz9C:xp+}%]0}+f-d
亦冇再深入諗個原理,所以亦局限咗自己,

而家知咗原理,就發現自己當時武斷地覺得太簡單了,是何其笨實.:D
