public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter n: ");
int n = in.nextInt();
double sum = 0.0;
for (int i = 1, j = 3; i <= n; i++, j+= 2)
sum += Math.pow(2, i) / j;
System.out.println("Sum = " + sum);

The Greatest Common Divisor (GCD) of two integers is calculated by the continued division method. Divide the larger number by the smaller, the remainder then divides the previous divisor. The process repeats unless the remainder reaches to zero. The last divisor results in GCD.
Sample Input: 45, 20
Sample Output: GCD=5Write a program to generate a triangle or an inverted triangle based upon user's choice of triangle to be displayed.
