Answer 1

What language?

Python:
num1, num2, num3 = 3, 5, 4
print(min(num1, min(num2, num3)))

C++:
#include <iostream>
#include <math.h>
using namespace std;

int main() {
int num1 = 3, num2 = 5, num3 = 4;
cout << min(num1, min(num2, num3));
return 0;
}

Java:
public class Program
{
public static void main(String[] args) {
int num1 = 3, num2 = 5, num3 = 4;
System.out.println(Math.min(num1, Math.min(num2, num3)));
}
}
