片面地追求数量而牺牲质量是错误的。
It is wrong to aim at sheer quantity at the expense of quality.
在生产中不要单纯地追求数量。
这会减少对后端数据库的请求数量。
This reduces the number of requests to the backend database.
We knew this was trying to do squaring, so intellectually we know we can square -4, it ought to be 16, but what happens here?
我们知道程序是用来求平方数的,那么按理说我们可以来求-4的平方,也就是16,但是程序结果是怎么样的呢?
I chose 22 because I thought that most people would play the game dividing by two-thirds a couple of times, and give numbers averaging around the low 30's.
我选了22因为我想大多数人在游戏中,可能会多次求平均数的2/3,最后会得出30以下的数
I'm given an integer that's a perfect square, and I want to write a little piece of code that's going to find the square root of it. All right so I'm cheating a little, I know it's a perfect square, somebody's given it to me, we'll come back in a second to generalizing it, so what would the steps be that I'd use to walk through it?
完美平方数的整数,我想写一段代码来求这个数的平方根,好,我这儿有点儿作弊了,我知道这是一个完美的平方数了,他们给我的,我们后面会讲怎么产生这个数的,那么我想解决这个问题,需要什么步骤呢?
