JavaScript实现的快速排序算法

function quickSort(arr) {
  if (arr.length <= 1) return arr;
  
  const pivot = arr[0];
  const left = [];
  const right = [];
  
  for (let i = 1; i < arr.length; i++) {
    if (arr[i] < pivot) {
      left.push(arr[i]);
    } else {
      right.push(arr[i]);
    }
  }
  
  return [...quickSort(left), pivot, ...quickSort(right)];
}

// 示例
const numbers = [64, 34, 25, 12, 22, 11, 90];
console.log(quickSort(numbers));

数据可视化

使用Matplotlib绘制简单折线图

import matplotlib.pyplot as plt
import numpy as np

# 创建数据
x = np.linspace(0, 10, 100)
y = np.sin(x)

# 创建图表
plt.figure(figsize=(10, 6))
plt.plot(x, y, label='正弦曲线', color='blue', linewidth=2)

# 添加标题和标签
plt.title('正弦函数曲线')
plt.xlabel('X轴')
plt.ylabel('Y轴')
plt.legend()

# 显示网格
plt.grid(True, alpha=0.3)

# 显示图表
plt.show()
