print(f"list.sort()平均时间: {sort_time:.6f}秒") 5.2 内存消耗考量 当处理大量数据时,内存使用成为一个重要因素。由于sorted()创建了一个新的列表,它会消耗双倍于原始数据的内存(在排序过程中)。相反,list.sort()就地排序,不增加额外的内存负担。如果你的工作环境对内存非常敏感,选择list.sort()更为合适。
* Slide elements over to make room for pivot.*/intn = start - left;//The number of elements to move//Switch is just an optimization for arraycopy in default case ,这个switch case用的非常讲究,当你明白了这个玩意,你就不得不佩服大佬,看看真正的大佬是如何把普通的东西玩出不一样switch(n) {...
