返回向量中的最大值和R中相关列中的字符串

vector = [1, 5, 3, 9, 2]
max_value = max(vector)
print(max_value)

int[] vector = {1, 5, 3, 9, 2};
int max_value = Arrays.stream(vector).max().getAsInt();
System.out.println(max_value);

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> vector = {1, 5, 3, 9, 2};
    int max_value = *std::max_element(vector.begin(), vector.end());
    std::cout << max_value << std::endl;
    return 0;
}

data <- data.frame(col1 = c("apple", "banana", "orange"), col2 = c("cat", "dog", "bird"))
related_strings <- data$col1
print(related_strings)

[1] "apple"  "banana" "orange"
