		Scanner scanner = new Scanner(System.in);
		System.out.println("Enter any NUMBER: ");
		int number = scanner.nextInt();
		System.out.println("Enter the POWER: ");
		int power = scanner.nextInt();
		scanner.close();
		// Logic for finding the POWER of number
		int powerOfNumber = (int) Math.pow(number, power);
		System.out.println("Power of a " + number + "^" + power + ": " + powerOfNumber);
	}
