The transpose of the linked list is a very common and basic data structure problem. The non-recursive algorithm is very simple. You can use three temporary pointers to loop through the linked list. Recursive Algorithms are also relatively simple, but it is difficult to write them out at half past one if the idea is unclear. The following is a recursive version of the linked list transpose program: [Cpp]# Include Using namespace std;Typedef struct Node{Node (int v, Node * ptr = NULL): data (v), n

That is, change the address to be written by FSMC to 0x60020000, as shown below:* (Volatile unsigned short int *) (0x60020000) = val;At this time, A16 will be pulled high while executing other FSMC, because the A0-A18 will present the address 0x60020000. In 0x60020000, Bit17 = 1, which causes A16 to be 1.To read data, change the address from 0x60020000 to 0x60000000. In this case, A16 is 0.
