Write todayCodeA strange problem occurs. The specific code is not pasted out, so you can write a simplified version. As follows:Arraylist String strings [] = (string []) List. toarray ();
In this way, I personally think there should be no problem in writing code, and there is no problem in compiling. However, an exception is reported during running, as follows: exce

Let's take a look at the following example. In this example, we want to get the square of each integer from 1 to 9 and put the result in the list to print it out.

Set two pointers (fast and slow). The initial values all point to the header. slow moves one step forward each time, and fast moves two steps forward each time. If the linked list has a ring, fast must first enter the ring, when s
The difference between a static list and a dynamic list:
Static linked lists and dynamic lists are two different representations of the linear chain-type storage structure.
1. Static linked lists are implemented in an array-like manner, are sequential storage structures, are contiguous on physical addresses, and need to be allocated in advance to the size of the address space. Therefore, the initial length
