letters is more than lowercase letters. Otherwise, if lowercase is greater or equal
to uppercase letters, print all lowercase. The inputs will contain letters (A-Z, a-z)
only.
Sample
Input
HOusE
ApplE
BaNaNa
Sample
Output
HOUSE
apple

Hello
Sample
Output
NUMBER
MIXED
WORD
3.In a given string, there will be two uppercase letters in between some lowercase
letters. Print the substring from the first uppercase letter to the last uppercase
letter excluding them. If there are no letters in between them, print the word
BLANK. It is guaranteed that there will be only two uppercase letters in the
string.
Sample Input baNgladEsh coDIng
Sample
Output glad
BLANK
4.Create a string from two given strings by concatenating common characters of
the given strings.

Nothing in common.
5. Again, you have lost your USIS password!! You went to the registrar office
and requested for a new password. This time, you need to follow some rules to
set your password. Otherwise, they won't change it. The rules are
At least one lowercase letter
At least one uppercase letter
At least one digit (0-9)
At least one special character (_ , $ , #, @)
Your task is to find whether a given password follows all those rules. If it breaks
any rule, you have to print Lowercase Missing, Uppercase Missing, Digit Missing
or Special Missing respective to the missing case. For more than one rule break,
print all the rules that were broken (order doesn't matter). If the password is ok,
print OK.
Sample Input
ohMyBR@CU
ohmybracu
OhMyBR@CU20
Sample Output
Digit missing
Uppercase character missing, Digit missing, Special character missing
OK
List
1. Write a python program which prints the frequency of the numbers that were given as
input by the user. Stop taking input when you find the string “STOP”. Do not print
the frequency of numbers that were not given as input.
Sample Input
10
20
20
30
10
50
90
STOP
Sample Output 10 - 2 times
20 - 2 times
30 - 1 times
50 - 1 times

and its respective list. Input starts with N and followed by N lists.
Sample Input 4
1 2 3
4 5 6
10 11 12
7 8 9
Sample Output 33
[10, 11, 12]
3. Let there are N numbers in a list and that list is said to be a UB
Jumper if the absolute values of the difference between the
successive elements take on all the values 1 through N − 1. For
example, 2 1 4 6 10 is a UB Jumper because the absolute
differences between them are 1 3 2 4 which is all numbers from 1 to
(5 - 1) or 4. Write a python program that takes a number sequence as input
and prints whether it is a UB Jumper or Not UB Jumper. Input will stop after
getting “STOP” as input. (Number order or absolute difference order doesn’t follow
any sequence.)
Sample Input
1 4 2 3
2 1 4 6 10
1 4 2 -1 6
STOP
Sample Output
UB Jumper
UB Jumper
Not UB Jumper
4. BRACU has n students who are regular competitive programmers. According
to the ACM ICPC rules, each person can participate in the regional championship
at most 5 times.
The head of the BRACU ACM Chapter is recently gathering teams to participate
in this championship. Each team must consist of exactly three people, at that, any
person cannot be a member of two or more teams. What maximum number of
teams can the head make if he wants each team to participate in the world
championship with the same members at least k times?
The first line of input contains two integers, n and k. The next line contains n
integers: y1,y2, ...,yn (0≤ yi≤ 5), where yi shows the number of times the i-thperson

Values: (200, 300, 400, 700)
2. Write a python program which prints the frequency of the numbers that were given as
input by the user. Stop taking input when you find the string “STOP”.Do not print
the frequency of numbers that were not given as input. Use a dictionary to solve the
problem
Sample Input 10
20
20
30

20 - 2 times
30 - 1 times 50 - 1 times
90 - 1 times
3. Write python code to invert a dictionary. It should print a dictionary where the keys are
values from the input dictionary and the values are lists of keys from the input
dictionary having the same value. Make sure the program handles multiple same
values.
Sample Input
key1 : value1, key2 : value2, key3 : value1
Sample Output
{"value1" : ["key1", "key3"], "value2" :
["key2"]}
4. On some basic cell phones, text messages can be sent using the numeric keypad.
Because each key has multiple letters associated with it, multiple key presses are
needed for most letters. Pressing the number once generates the first character listed
for that key. Pressing the number 2, 3, 4 or 5 times generates the second, third, fourth
or fifth character.
Key Symbols

Function
1. You are one of the gym instructors at AmiKenoMota. You decide to provide a
customized diet and exercise plans based on the BMI of an individual. You
measure the weight in kilograms and height in meters and calculate the BMI
before a plan can be decided. Write a BMI function that takes in two values,
weight in kg and height in cm and print the score along with the condition. (Make
sure to convert cm into m before calculation)
BMI(height, weight)
������ = ����/��2
Based on the BMI score return the following output.
● < 18.5- Underweight
● 18.5 - 24.9 - Normal
● 25 -30 - Overweight
● > 30 – Obese
Sample Input (175, 96)
(152, 48)
Sample Output
Score is 31.3. You are Obese Score is 20.8. You are
Normal

4. A company named Sheba.xyz has recently moved from their old domain to
a new domain. However, a lot of the company email addresses are still using
the old one. Write a function in python that replaces this old domain with the
new
one in any outdated email addresses. Keep same if the email address contains
the new domain. (Do not use builtin replace function)
Firstly, define a “replace_domain” function which accepts three
parameters *The email address to be checked
*The new domain
* The old domain (Use Default argument technique to handle this)
Sample Input
(‘alice@kaaj.com’, ‘sheba.xyz’, ‘kaaj.com’)
(‘bob@sheba.xyz’, ‘sheba.xyz’)
Sample Output
Changed: alice@sheba.xyz Unchanged: bob@sheba.xyz
5. Write a programwhich checks whether a given string is a palindrome or not.
Note: A palindrome is a word, phrase, or sequence that reads the same backward
as forward. For palindrome, any spaces in middle are not considered and should
be trimmed.
Sample Input ‘madam’
‘hello’
‘nurses run’
Sample Output Palindrome
Not a palindrome Palindrome
6. You are a class teacher at a kindergarten school. As a task, you asked your
students to write a paragraph. Unfortunately, you notice that most of the students
did not use capital letters correctly. Your task is to write a function which takes a
string as its only parameter and returns a new copy of the string that has been
correctly capitalized. Your function should:
● Capitalize the first letter in the string
● Capitalize the first letter after a full-stop, exclamation mark or questionmark
● Capitalize the word “i” if it is in lowercase.
Summary: You have to write a function that reads a string from the user
and capitalizes. The string is then returned and displayed.
Sample Input
('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily.
do you know my pet dog’s name? i love my pet very much.')
Sample Output
My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do
you know my pet dog’s name? I love my pet very much.
