引言
逆序是一種罕見的編程技能，它可能在各種場景下利用，比方處理數組、字元串等。在C言語中，逆序操縱可能經由過程多種方法實現，本文將介紹多少種罕見的逆序技能，幫助讀者輕鬆控制高效代碼實現。
1. 逆序數組
逆序數組是最基本的逆序操縱之一。以下是一種利用C言語實現數組逆序的示例代碼：
#include <stdio.h>
void reverseArray(int arr[], int size) {
int temp;
for (int i = 0; i < size / 2; i++) {
temp = arr[i];
arr[i] = arr[size - 1 - i];
arr[size - 1 - i] = temp;
}
}
int main() {
int array[] = {1, 2, 3, 4, 5};
int size = sizeof(array) / sizeof(array[0]);
printf("Original array:\n");
for (int i = 0; i < size; i++) {
printf("%d ", array[i]);
}
printf("\n");
reverseArray(array, size);
printf("Reversed array:\n");
for (int i = 0; i < size; i++) {
printf("%d ", array[i]);
}
printf("\n");
return 0;
}
2. 逆序字元串
在C言語中，字元串也可能經由過程逆序操縱來改變其次序。以下是一個逆序字元串的示例代碼：
#include <stdio.h>
#include <string.h>
void reverseString(char *str) {
int len = strlen(str);
for (int i = 0; i < len / 2; i++) {
char temp = str[i];
str[i] = str[len - 1 - i];
str[len - 1 - i] = temp;
}
}
int main() {
char str[] = "Hello, World!";
printf("Original string: %s\n", str);
reverseString(str);
printf("Reversed string: %s\n", str);
return 0;
}
3. 逆序鏈表
鏈表是一種常用的數據構造，逆序鏈表也是一種罕見的操縱。以下是一個逆序鏈表的示例代碼：
#include <stdio.h>
#include <stdlib.h>
struct Node {
int data;
struct Node* next;
};
void reverseLinkedList(struct Node** headRef) {
struct Node* prev = NULL;
struct Node* current = *headRef;
struct Node* next = NULL;
while (current != NULL) {
next = current->next;
current->next = prev;
prev = current;
current = next;
}
*headRef = prev;
}
void printLinkedList(struct Node* node) {
while (node != NULL) {
printf("%d ", node->data);
node = node->next;
}
printf("\n");
}
int main() {
struct Node* head = NULL;
struct Node* second = NULL;
struct Node* third = NULL;
head = (struct Node*)malloc(sizeof(struct Node));
second = (struct Node*)malloc(sizeof(struct Node));
third = (struct Node*)malloc(sizeof(struct Node));
head->data = 1;
head->next = second;
second->data = 2;
second->next = third;
third->data = 3;
third->next = NULL;
printf("Original linked list: ");
printLinkedList(head);
reverseLinkedList(&head);
printf("Reversed linked list: ");
printLinkedList(head);
return 0;
}
