Programming Practice:
Q1. Write a program to generate this series (n terms):
Q2. Write a program to print whether number entered is Armstrong number or not.
Hint : An Armstrong number (also called a narcissistic number, pluperfect digital invariant (PPDI), or pluperfect number) is a
number that is equal to the sum of its own digits raised to the power of the number of digits.
Q3. Write a program to print whether number entered is prime number or not.
Q4. Write a program to print whether number entered is perfect number or not.
Q5. Write a program to input marks and print Grade as per rules:
90 and above → Grade A
75–89 → Grade B
50–74 → Grade C
Below 50 → Grade D
