Q1: Write a program to define a function multiply which get two parameters and returns the product of them.

---

Q2: Write a program to create a function that gets sides of a rectangle and return its perimeter and area.

---

Q3: Write a program to create a function that gets a number n and a value s and prints the value n times as output.

Sample 1:
I/P:
10
Hello

O/P:
Hello
Hello
Hello
Hello
Hello
Hello
Hello
Hello
Hello

Q4: Write a program to define a function to determine simple interest for given values of Principal, Rate p.a. and duration in years.
Simple Interest, S.I. = ${\displaystyle \frac{P\times R\times T}{100}}$

---

Q5: Write a program to get a number n and and print the prime numbers from 1 to n. Use function to check if a number is prime or not.

---

Q6: Write a program to define a function to return factorial of the number passed in it (use recursion).

---

Q7: Write a program to define a function to return factorial of the number passed in it (without recursion).

---

Q8: Write a program to define a function that gets a year as input and print if it is a leap year or not.

Condition: A year is leap if it is either divisible 4 or 400 and not 100.

---

Q9: Write a program to define a function that returns the permutation of n and r.
$\text{Permutation(n, r)}={}^n{P}_r={\displaystyle \frac{n!}{(n-r)!}}$

---

Q10: Write a program to define a function that returns the permutation of n and r. Use recursion to compute the factorials.
$\text{Permutation(n, r)}={}^n{P}_r={\displaystyle \frac{n!}{(n-r)!}}$

---

Q11: Write a program to define a function that returns the permutation of n and r.
$\text{Permutation(n, r)}={}^n{P}_r$ = ${\displaystyle \frac{n!}{(n-r)!}}=n(n-1)(n-2)...r\text{terms}$

---

Q12: Write a program to define a function that returns the combination of n and r.
$\text{Combination(n, r)}={}^n{C}_r={\displaystyle \frac{n!}{(n-r)!r!}}$

---

Q13: Write a program to define a function that returns the combinations of n and r. Use recursion to compute the factorials.
$\text{Combination(n, r)}={}^n{C}_r={\displaystyle \frac{n!}{(n-r)!r!}}$

---

Q14: Write a program to define a function that returns the combinations of n and r.
$\text{Combination(n, r)}={}^n{C}_r={\displaystyle \frac{n!}{(n-r)!r!}}={\displaystyle \frac{n(n-1)(n-2)...r\text{terms}}{1\times 2\times 3...r\text{(r terms)}}}={\displaystyle \prod _{i=0}^{r-1}{\displaystyle \frac{n-i}{i+1}}}$
