$1.$ Write a program with a while loop that will display numbers in the range $1$ to $30,$ divisible by $3.$

$2.$ Prepare a program that prints even numbers in the range $1$ to $30.$ Use a for loop and a continue

statement.

$3.$ Prepare an alphabet function that takes the letter x as an argument and displays the letters $\text{'}$a$\text{'}$ to x$.$

Use a while loop.

$4.$ Write a program that uses do $-$ while statements to add integers from $1$ to x$.$

$5.$ Prepare a function that uses the for statement to sum the even numbers in the range $0$ to x$.$

Use the modulo$\%$ operator.

$6.$ Prepare a program that displays numbers from $-100$ to $100$ in descending order. Numbers

should be divisible by $2,$ but not divisible by $3$ and $8.$ Complete the task using the continue

statement.

$7.$ During the ski jumping competition the competitor receives style marks from $5$ judges. The

final grade for style is equal to the sum of the three that will remain after rejecting the extreme marks $($i$.$e$.$ the smallest and the largest$).$ Write a program that reads $5$ numbers from $0$

to $20$ into an array, and then calculates the style marks according to the rules above.

$8.$ Write an algorithm that will fill the square table as shown below and display n rows and columns.

Below is an example for n equal to $5$

$11111$

$12222$

$12333$

$12344$

$12345$

$9.$ Implement the algorithm that calculates the fibonacci numbers using the recursive and iterative method
