Program Explanation

1. Get three inputs num1,num2 and num3 from user using scanner class.

2. check whether num1 is smaller than num2 and num1 is smaller than num3 using if statement.

    if num1 is smaller

        2a. print num1 using print statment,

    else

        2b. check whether num1 is smaller than num3 using elseif statement.

        If num2 is smaller

            2b1. print num2 using system.out.println,

        else

            2b2. print num3 using system.out.println.
