package com.codegym.task.task02.task0216; /* Minimum of three numbers */ public class Solution { public static int min(int a, int b, int c) { //write your code here int m2; if (c < b && c < a) m2 = c; else if (b < c && b <a) m2 = b; else m2 = a; } public static void main(String[] args) throws Exception { System.out.println(min(1, 2, 3)); System.out.println(min(-1, -2, -3)); System.out.println(min(3, 5, 3)); System.out.println(min(5, 5, 10)); } }
