Sum of the minimum and the maximum of three integers

Write a program that reads three numbers and prints the sum of their minimum and maximum values. 

Input : Input consists of three integer numbers.

Output : Print a line with the sum of the maximum and the minimum of the three numbers.

#include <iostream>
using namespace std;

int main() {
    int l, m, n;
    cin >> l >> n >> m;
    int max, min;
    if (n < l and n < m) min = n;
    else if (m < n and m < l) min = m;
    else min = l;
    
    
    if (n > l and n > m) max = n;
    else if (m > n and m > l) max = m;
    else max = l;
    
    cout << max+min << endl;
