“是一个10个number 的sequence, from the second number is 1 less than sum of the precedingnumber, the first two number is odd. How many number in this ten-numbersequence is even? 答案有 3,4,5,7,8…我当时怎么算怎么觉得是0啊,前两奇数那奇+奇再减一不是还是奇吗??那就是一直奇奇奇奇奇奇奇奇奇奇啊!!!有么有有么有!!比如 1,3,3,5,….这样下去啊…最后无比崩溃的随便选了7 (原因是7是我的幸运数字!可以明白我当时是有多无奈啊!!)求各位牛人看看到底哪里犯了幼稚的错误…”
多谢lz分享!污染那篇,opportunity cost为什么不是allocate resource more effciently? opportunity cost既然代表wasted resources ,wasted effort,污染也代表生产过程有缺陷~

貌似它题目问的是 "OPPORTUNITY COST"指的是什么,然后wiki对原始OC的解释是“ the cost of any activity measured in terms of the best alternative forgone.” 我想这里就是指 the cost of pollution, if use the best alternative, there will be no such cost. 如果没有pollution 就应该是没有这些waste 那就应该是Pollution的Lost. 这是我的感觉...当然考试时间紧张 然后一个方向想错 就错了....
