frequency_sort(['bob', 'bob', 'carl', 'alex', 'bob']) == ['bob', 'bob', 'bob', 'carl', 'alex'] 代码思路 先对序列中的元素出现的频率进行统计,考虑到collections模块中的Counter函数可以进行相关的统计,返回的一个Counter对象,如下例子 ...
The following function always returns either a -1 or a 1, which I assumed at first would always rearrange the items in the array: function () { if (Math.random()<.5) return -1; else return 1; } This is the new order of our original list, sorted 100 times using this method: ...
