insert: 直接加在hash map对应的list末尾和arraylist的末尾 delete: 和最后一个元素交换,再删除最后一个元素。注意如果map.get(val)只有一个元素的时候,要把map中对应的val删除 classRandomizedCollection { Map<Integer, List<Integer>>map; List<int[]>list; ...
1. 随机读取一个数的话,使用数组的时间复杂度是最小的,因为通过下标可以直接定位。考虑到元素会不断插入,我们可以选择ArrayList来存储我们的元素。 2. 要删除一个元素,在数组中需要遍历才能找到这个元素。而在HashMap中,可以快速定位一个元素。因此我们可以用HashMap来存储元素和它在ArrayList中对应的下标。
The NumPy library offers a user-friendly function called `delete` to achieve this task. The numpy.delete() function is capable of removing elements in an array, along a specified axis. This makes it simple for us to delete a column from a 2D array or a matrix. ...
