行程问题编程代码可以根据不同的需求和场景进行编写。以下是一些示例代码,分别使用Python和C语言实现:
Python 示例代码
```python
from geopy.geocoders import Nominatim
from datetime import date, timedelta
import networkx as nx
初始化geolocator
geolocator = Nominatim(user_agent="my_trip_planner")
查询目的地经纬度
location = geolocator.geocode("北京")
print(location.latitude, location.longitude)
旅行开始时间和时长
start_date = date(2024, 12, 20)
duration = 7
生成旅行日期
for i in range(duration):
current_date = start_date + timedelta(days=i)
print(f"第{i+1}天: {current_date}")
创建一个图表示城市之间的连接
G = nx.Graph()
假设我们有几个城市和它们之间的连接
G.add_edge('城市A', '城市B', weight=100)
打印图的信息
print(G.nodes())
print(G.edges())
```
C 示例代码
简单的行程编码
```c
include include void RLE(char target[]) { int Chcount = 0; int Repcount = 0; char temp; char ch; for (int i = 0; target[i] != '\0'; i++) { ch = target[i]; Chcount++; if (Repcount == 0) { Repcount++; temp = ch; } else { if (temp == ch) { Repcount++; } else if (Repcount >= 4) { Chcount = Chcount - Repcount - 1; target[Chcount] = Repcount + '0'; target[Chcount + 1] = temp; Chcount += 3; target[Chcount] = ch; Chcount++; Repcount = 1; temp = ch; } else { temp = ch; Repcount = 1; } } } if (Repcount >= 4) { Chcount = Chcount - Repcount - 1; target[Chcount] = Repcount + '0'; target[Chcount + 1] = temp; Chcount += 2; } } int main() { char input[] = "aaaaaabcccc12344"; RLE(input); printf("压缩后为: %s\n", input); return 0; } ``` 简单的追击和逃跑路程问题 ```c include int main() { int distance, time; int speed1, speed2; int time1, time2; int distance1, distance2; printf("请输入甲车的速度(千米/小时):"); scanf("%d", &speed1); printf("请输入乙车的速度(千米/小时):"); scanf("%d", &speed2); printf("请输入甲车先行的时间(小时):"); scanf("%d", &time1); printf("请输入两车相遇的时间(小时):"); scanf("%d", &time2); distance1 = speed1 * time1 + speed2 * time2; distance2 = speed1 * time2 + speed2 * time1; printf("甲车行驶的总距离为:%d 千米\n", distance1); printf("乙车行驶的总距离为:%d 千米\n", distance2); return 0; } ``` 这些代码示例分别展示了如何使用Python进行行程规划、如何使用C语言进行简单的行程编码以及追击和逃跑的路程问题。你可以根据具体需求选择合适的代码进行参考和修改。
