Write a program that accepts student mark out of 100, and return the corresponding letter grade based on the following condition:

if mark is greater than or equal to 90 A

if mark is greater than or equal to 80 and less than 90B

if mark is greater than or equal to 60 and less than 80C

if mark is greater than or equal to 40 and less than 60D

if mark is less than 40F

for other cases NG

It is known that a score for a given course is b/n 0-100

Write a program that gives the maximum value from an array with size 8. The data stored in the array should be accepted from the user and should be an integer value. Write another program which orders the same data in an ascending order

1 Write a program which inputs a person’s height (in centimetres) and weight (in kilograms) and outputs one of the messages: underweight, normal, or overweight, using the criteria:

Underweight: weight < height/2.5

Normal: height/2.5 <= weight <= height/2.3

Overweight: height/2.3 < weight

Create a method named getCircleDiameter that takes a radius of double type as the parameter. The method should return the diameter of a circle. To compute the diameter of a circle, multiply the radius by 2.

Python Problem Solving

You're given a positive integer: Perform the sequence of operations as per below guidelines until the value reaches 1:

If N is even --> N / 2

If N is odd --> N * 3 + 1

Print the total number of steps it took to reach 1.

Input

The first line of input contains an integer.

Output

The output should be a single integer denoting the total number of steps.

Explanation

For Example, using N = 10 as the input, with 6 steps.

10 is even - 10/2 = 5

5 is odd - 5 * 3 + 1 = 16

16 is even - 16 / 2 = 8

8 is even - 8 /2 = 4

4 is even - 4/2 = 2

2 is even - 2/2 = 1 --> Reached 1.

So the output should be 6.

Python Program

Write a python program to print the following output.

Input

The first line contains a string S representing a unique id.

The second line contains an integer N representing group length.

Output

The output should be a single string representing the new unique id.

Sample Input1

Sample Output1

24-A0R-74K

Python Program

Write a program to print the following, Given a word W and pattern P, you need to check whether the pattern matches the given word.The word will only contain letters(can be Uppercase and Lowercase). The pattern can contain letters, ? and *.

? : Can be matched with any single letter.

* : Can be matched with any sequence of letters (including an empty sequence).

If the pattern matches with the given word, print True else False.

Sample Input1

3

Hello *l?

Hell He?ll

Hell ?*

Sample Output1

True

False

True

Sample Input1

3

Hello Hell*

Hell He*ll

Hell hell*

Sample Output1

True

True

False

Write a program to print the following output.

Input

The first line contains a string.

The second line contains some space-separated strings.

Output

The output should be a single integer.

Explanation

scramble word = "tacren"

guessed words = ["trance", "recant"]

Since "trance" and "recant" both have length 6 then you score 54 pts each.

So the output is 108.

Sample Input1

rceast

cat create sat

Sample Output1

2

Sample Input2

tacren

trance recant

Sample Output2

108
