分享者: python_devimport 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()JavaScript实现的快速排序算法
分享者: adminfunction 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));
