度之 謎 章
If anyone knows the answer, please answer below with reverse type.
回復之答案請反白。
You have 4 stones.
They are of four distinct colors, and they are also of distinct weights of 1, 2, 3, 4 grams.
However, you do not know which weight corresponds to which color.
The balance scale you have can only indicate which side is heavier or whether the two sides are balanced, without further details.
You may put as many stones as you want on each side of the scale.
What is the least number of weighing trials needed to ensure correct weight labeling for all stones?
你有四顆石頭。
每顆石頭都有不同顏色，以及不同的重量。
四顆石頭的重量分別是 1，2，3，4g。
但是你不知道每一顆石頭的重量。
你需要利用這一個天秤來量度出每一個石頭的重量，而這個天秤時沒有數字的（正常......）。
你需要最少多少次來量度出每一顆石頭的重量呢？
如果有人看得明上圖的話，則是一個極大的提示（？）
