有个智力测验是这样的:有两只完全相同的水龙头,每只龙头注满一桶水费时2分钟,现有三只同样的空桶A、B、c,请问将桶全部注满最少几分钟?如果将任意两桶先注满,再注满余下的一桶,那么答案是4分钟。如果在第一分钟内对A、B桶同时注水,在第二分钟内用C桶换走B桶而A桶不动,在第三分钟内用B桶换走A桶,那么答案是3分钟。可见,通过优化操作流程可以更加充分地利用资源提高流程运行效率和运行速度(但操作步骤已由两步增加为三步)。
There is a mental test is this: There are two identical faucet, each faucet filled with a bucket of water for 2 minutes, the existing three empty bucket A, B, c, Will the barrel filled with a minimum of a few minutes If you fill any two buckets first and fill the remaining bucket, the answer is 4 minutes. If in the first minute on the A, B bucket at the same time, in the second minute with the C bucket in exchange for B bucket A bucket does not move, in the third minute with bucket B for A bucket, then the answer is 3 minutes . Visible, optimize the operation process can be more fully utilized resources to improve the efficiency and speed of the operation of the process (but steps have been increased from two steps to three steps).
