数字交互的发展历程

在计算机编程中，要找出两个集合中相同的元素（即交集），可以使用不同的编程语言实现。以下是一些常见的编程语言的示例代码：

Python

```python

set1 = {1, 2, 3, 4, 5}

set2 = {4, 5, 6, 7, 8}

intersection = set1.intersection(set2)

print(intersection)

```

JavaScript

```javascript

const set1 = new Set([1, 2, 3, 4, 5]);

const set2 = new Set([4, 5, 6, 7, 8]);

const intersection = new Set(

[...set1].filter(x => set2.has(x))

);

console.log(intersection);

```

Java

```java

Set set1 = new HashSet<>(Arrays.asList(1, 2, 3, 4, 5));

Set set2 = new HashSet<>(Arrays.asList(4, 5, 6, 7, 8));

set1.retainAll(set2);

System.out.println(set1);

```

C

```cpp

include

include

include

include

int main() {

std::set set1 = {1, 2, 3, 4, 5};

std::set set2 = {4, 5, 6, 7, 8};

std::vector intersection;

std::set_intersection(set1.begin(), set1.end(), set2.begin(), set2.end(), std::back_inserter(intersection));

for (int num : intersection) {

std::cout << num << " ";

}

return 0;

}

```

这些代码示例展示了如何在Python、JavaScript、Java和C 中找出两个集合的交集。根据你的需求，选择合适的编程语言和方法来实现数字交集的计算。
