第一章：代碼之城的召集令

在遙遠的數字大陸上，有一座名為“代碼之城”的神秘都市。這里居住著各種編程語言的化身，他們以擬人化的形態生活，每種語言都有獨特的性格與技能。Python是個優雅的學者，C++是個硬核戰士，JavaScript是個靈動的弄潮兒，而Rust則是個嚴謹的衛兵……這座城市每年都會舉辦一場盛大的“編程之巔”大賽，決出最強的語言之王。

這一年，代碼之城的中央廣場上，巨大的全息屏幕亮起，發布了一則召集令：

📜 編程之巔大賽召集令 📜
所有編程語言，速來競技場！
規則：通過實戰項目比拼，展現速度、效率與創造力。
獎品：代碼王冠，統治代碼之城一年！

消息一出，城市沸騰了。Python捋了捋他的長袍，微笑著說：“優雅與簡潔，定能勝出。”C++磨了磨手中的巨劍，冷哼道：“只有力量與速度才是王道。”JavaScript跳上桌子，甩了甩金色的卷發：“靈活才是未來，兄弟們，沖啊！”而Rust則默默檢查著自己的防銹盔甲，平靜道：“安全第一，穩中求勝。”

第二章：初賽——迷宮挑戰

大賽的第一關是“迷宮挑戰”。參賽者需要編寫代碼，控制一個虛擬探險者在復雜迷宮中找到出口。迷宮布滿陷阱，代碼必須兼顧速度與正確性。

Python率先登場。他打開一本厚厚的算法書，優雅地敲下一段代碼：

def find_path(maze, start, end):from collections import dequequeue = deque([(start, [start])])visited = set()while queue:(x, y), path = queue.popleft()if (x, y) == end:return pathif (x, y) in visited:continuevisited.add((x, y))for dx, dy in [(0, 1), (1, 0), (0, -1), (-1, 0)]:nx, ny = x + dx, y + dyif 0 <= nx < len(maze) and 0 <= ny < len(maze[0]) and maze[nx][ny] == 0:queue.append(((nx, ny), path + [(nx, ny)]))return Nonemaze = [[0, 1, 0, 0],[0, 1, 0, 1],[0, 0, 0, 0],[1, 1, 0, 0]
]
path = find_path(maze, (0, 0), (3, 3))
print("Python's Path:", path)

Python的代碼簡潔易讀，探險者迅速找到出口，觀眾席爆發出掌聲。“這就是簡潔的力量！”Python得意地推了推眼鏡。

C++不屑地撇嘴，拔出巨劍，敲出一段復雜但高效的代碼：

#include <vector>
#include <queue>
#include <utility>
using namespace std;vector<pair<int, int>> findPath(vector<vector<int>>& maze, pair<int, int> start, pair<int, int> end) {int rows = maze.size(), cols = maze[0].size();vector<vector<bool>> visited(rows, vector<bool>(cols, false));queue<pair<pair<int, int>, vector<pair<int, int>>>> q;q.push({start, {start}});int dirs[4][2] = {{0, 1}, {1, 0}, {0, -1}, {-1, 0}};while (!q.empty()) {auto [pos, path] = q.front();q.pop();int x = pos.first, y = pos.second;if (pos == end) return path;if (visited[x][y]) continue;visited[x][y] = true;for (auto& dir : dirs) {int nx = x + dir[0], ny = y + dir[1];if (nx >= 0 && nx < rows && ny >= 0 && ny < cols && maze[nx][ny] == 0) {vector<pair<int, int>> newPath = path;newPath.push_back({nx, ny});q.push({{nx, ny}, newPath});}}}return {};
}

C++的探險者以驚人的速度沖出迷宮，比Python快了整整0.01秒！觀眾驚嘆：“這就是性能之王！”C++冷笑：“優雅？不過是花架子。”

JavaScript跳躍著上場，甩出一段充滿異步魔法的代碼：

async function findPath(maze, start, end) {const queue = [[start, [start]]];const visited = new Set();const directions = [[0, 1], [1, 0], [0, -1], [-1, 0]];while (queue.length) {const [[x, y], path] = queue.shift();if (x === end[0] && y === end[1]) return path;if (visited.has(`${x},${y}`)) continue;visited.add(`${x},${y}`);for (const [dx, dy] of directions) {const nx = x + dx, ny = y + dy;if (nx >= 0 && nx < maze.length && ny >= 0 && ny < maze[0].length && maze[nx][ny] === 0) {queue.push([[nx, ny], [...path, [nx, ny]]]);}}await new Promise(resolve => setTimeout(resolve, 0)); // 模擬異步}return null;
}const maze = [[0, 1, 0, 0],[0, 1, 0, 1],[0, 0, 0, 0],[1, 1, 0, 0]
];
findPath(maze, [0, 0], [3, 3]).then(path => console.log("JS Path:", path));

JavaScript的探險者邊跳舞邊找路，觀眾看得眼花繚亂。雖然速度稍慢，但他的代碼充滿了現代感，博得一片喝彩。

Rust沉穩地上場，檢查了所有邊界條件后，提交了安全無懈可擊的代碼：

use std::collections::VecDeque;fn find_path(maze: &Vec<Vec<i32>>, start: (usize, usize), end: (usize, usize)) -> Option<Vec<(usize, usize)>> {let mut queue = VecDeque::new();let mut visited = vec![vec![false; maze[0].len()]; maze.len()];queue.push_back((start, vec![start]));let directions = [(0, 1), (1, 0), (0, -1), (-1, 0)];while let Some(((x, y), path)) = queue.pop_front() {if (x, y) == end {return Some(path);}if visited[x][y] {continue;}visited[x][y] = true;for &(dx, dy) in directions.iter() {let nx = x as i32 + dx;let ny = y as i32 + dy;if nx >= 0 && nx < maze.len() as i32 && ny >= 0 && ny < maze[0].len() as i32 && maze[nx as usize][ny as usize] == 0 {let mut new_path = path.clone();new_path.push((nx as usize, ny as usize));queue.push_back(((nx as usize, ny as usize), new_path));}}}None
}

Rust的探險者穩扎穩打，沒有觸發任何陷阱，安全抵達終點。觀眾贊嘆：“這代碼，固若金湯！”

初賽結果公布：C++以速度取勝，Python、Rust緊隨其后，JavaScript因異步風格加分，全部晉級。

第三章：決賽——構建未來之城

決賽的主題是“構建未來之城”。參賽者需編寫一個程序，模擬城市規劃，優化資源分配、建筑布局和交通網絡。這需要綜合運用算法、并發處理和創造力。

Python選擇用數據分析驅動規劃。他調用Pandas和NumPy，優雅地優化資源：

import pandas as pd
import numpy as npdef plan_city(buildings, resources, population):df = pd.DataFrame(buildings, columns=['x', 'y', 'type', 'cost'])resource_limits = pd.Series(resources, index=['water', 'power', 'food'])# 優化建筑布局distances = np.sqrt((df['x'] - df['x'].mean())**2 + (df['y'] - df['y'].mean())**2)df['distance_score'] = distancesoptimized_layout = df.sort_values('distance_score').head(int(population * 0.8))# 分配資源allocation = resource_limits * (optimized_layout['cost'] / optimized_layout['cost'].sum())return optimized_layout, allocation.to_dict()buildings = [[10, 20, 'hospital', 100],[15, 25, 'school', 50],[5, 10, 'house', 20]
]
resources = {'water': 1000, 'power': 500, 'food': 800}
layout, allocation = plan_city(buildings, resources, 1000)
print("Python's City Plan:", layout, allocation)

Python的規劃科學而高效，城市布局井然有序，資源分配均衡，觀眾為之傾倒。

C++選擇用多線程并行計算，追求極致性能：

#include <vector>
#include <thread>
#include <mutex>
#include <cmath>struct Building {double x, y;string type;int cost;
};void optimize_layout(const vector<Building>& buildings, vector<Building>& result, int start, int end, mutex& mtx) {vector<pair<double, Building>> scores;double cx = 0, cy = 0;for (const auto& b : buildings) {cx += b.x; cy += b.y;}cx /= buildings.size(); cy /= buildings.size();for (int i = start; i < end; ++i) {double dist = sqrt(pow(buildings[i].x - cx, 2) + pow(buildings[i].y - cy, 2));scores.push_back({dist, buildings[i]});}lock_guard<mutex> lock(mtx);result.insert(result.end(), scores.begin(), scores.end());
}vector<Building> plan_city(const vector<Building>& buildings, int population) {vector<Building> result;mutex mtx;vector<thread> threads;int chunk = buildings.size() / 4;for (int i = 0; i < 4; ++i) {int start = i * chunk;int end = (i == 3) ? buildings.size() : start + chunk;threads.emplace_back(optimize_layout, ref(buildings), ref(result), start, end, ref(mtx));}for (auto& t : threads) t.join();return result;
}

C++的規劃速度驚人，城市在幾毫秒內成型，觀眾驚呼：“這效率，無人能敵！”

JavaScript則用Web技術打造動態城市，實時響應用戶需求：

class CityPlanner {constructor(buildings, resources, population) {this.buildings = buildings;this.resources = resources;this.population = population;}async plan() {const center = this.buildings.reduce((acc, b) => ({x: acc.x + b.x / this.buildings.length,y: acc.y + b.y / this.buildings.length}), {x: 0, y: 0});const layout = this.buildings.map(b => ({...b,distance: Math.sqrt((b.x - center.x)**2 + (b.y - center.y)**2)})).sort((a, b) => a.distance - b.distance).slice(0, Math.floor(this.population * 0.8));const totalCost = layout.reduce((sum, b) => sum + b.cost, 0);const allocation = Object.fromEntries(Object.entries(this.resources).map(([k, v]) => [k, v * (totalCost / layout.length)]));return { layout, allocation };}
}const planner = new CityPlanner([{x: 10, y: 20, type: 'hospital', cost: 100}, ...],{water: 1000, power: 500, food: 800},1000
);
planner.plan().then(result => console.log("JS City Plan:", result));

JavaScript的城市充滿互動性，居民可以實時調整布局，觀眾歡呼：“這才是用戶體驗！”

Rust則以安全為核心，設計了一個永不崩潰的城市系統：

struct Building {x: f64,y: f64,building_type: String,cost: i32,
}struct CityPlan {layout: Vec<Building>,resources: HashMap<String, f64>,
}fn plan_city(buildings: Vec<Building>, resources: HashMap<String, f64>, population: usize) -> Option<CityPlan> {let center_x: f64 = buildings.iter().map(|b| b.x).sum::<f64>() / buildings.len() as f64;let center_y: f64 = buildings.iter().map(|b| b.y).sum::<f64>() / buildings.len() as f64;let mut scored: Vec<(f64, Building)> = buildings.into_iter().map(|b| {let dist = ((b.x - center_x).powi(2) + (b.y - center_y).powi(2)).sqrt();(dist, b)}).collect();scored.sort_by(|a, b| a.0.partial_cmp(&b.0).unwrap());let layout = scored.into_iter().take((population as f64 * 0.8) as usize).map(|(_, b)| b).collect();let total_cost: i32 = layout.iter().map(|b| b.cost).sum();let allocation = resources.into_iter().map(|(k, v)| (k, v * (total_cost as f64 / layout.len() as f64))).collect();Some(CityPlan { layout, resources: allocation })
}

Rust的城市固若金湯，資源分配滴水不漏，觀眾感嘆：“這安全感，無與倫比！”
