C++ 算法：求整数序列的最大值和最小值之差

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

int main() {
    int M;
    std::cin >> M;

    std::vector<int> nums(M);

    for (int i = 0; i < M; i++) {
        std::cin >> nums[i];
    }
    
    int min_num = *std::min_element(nums.begin(), nums.end());
    int max_num = *std::max_element(nums.begin(), nums.end());
    
    int diff = max_num - min_num;

    std::cout << diff << std::endl;

    return 0;
}
