return 2 * 3.14 * radius;
}
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
Double r = sc.nextDouble();
System.out.println(getCircumference(radius));
}
}
Take an array of numbers as input and check if it is an array sorted in ascending order.
Eg : { 1, 2, 4, 7 } is sorted in ascending order.
{3, 4, 6, 2} is not sorted in ascending order.
