重复调用下面的更新操作会收敛于x的平方根: >>> def average(x, y): return (x + y)/2 >>> def sqrt_update(guess, x): return average(guess, x/guess) 1. 2. 3. 4. 这个带有两个参数的更新函数和iter_improve不兼容,并且它只提供了一个介值。我们实际上只关心最后的平方根

The pair correlation function is almost uniform for this distribution of particles. Because the particles are randomly located and not tightly packed, they have essentially no structure. g(r) is zero for r<1 because the particles have radius one and they are not allowed to overlap. ...
(https://leetcode.com/problems/valid-perfect-square/solution/)。 简单来说:我们创建左右两个指针,并比较原数字与这两个指针指向数字的平均值(average value)。如果它小于原数,就增加它的值;如果是大于,我们就减少它的值;如果相等,就返回True。 我们使用while循环(while loop)来对这些情况进行自动检查。
