Input & Output
Q-1 : Hello World
This is the very first program in the
programming language., this file contains the declaration of print function.
print is used to display the message as well as the value on the standard
output device (monitor), use of print function is very easy, you have to just
pass the string (message) that you want to print on the screen within inverted
commas ("message").
Sample Output:
Hello World
Program:
print("Hello World")
Q-2 : Hello world with tab
There are few escape
sequences which is used for formatting the output in the c programming
language, you have to use \t escape sequence in order to provide 4 to 5 spaces
between words in the output console. Enter the escape sequence directly into
the print statement's within the inverted commas ("mes\tsage").
Sample Output:
Hello World Hello World
Program:
print("Hello World Hello World")
Q-3 : Hello world with new
line
There are few escape
sequences which is used for formatting the output in programming language, you
have to use \n escape sequence in order to provide a new line between words in
the output console. Enter the escape sequence directly into the print
statement's within the inverted commas ("mes\nsage").
Sample Output:
Hello World
Hello World
Program:
print("Hello World\nHello World")
Q-4 : Character Input
Python programming has
several in-built functions to perform input and output tasks. Two commonly used
functions for I/O (Input/Output) are print and raw_input().. Write a program to
get a character as input and print it. The raw_input() function reads formatted
input from the keyboard. When the user enters a character, it is stored in
variable testCharacter. NOTE: Bold letters or words are Input and rest are
output statements.

Q-7 : String Input
Python programming has several in-built functions to perform
input and output tasks. Two commonly used functions for I/O (Input/Output) are
print and raw_input(). Write a program to get the string as input and print it.
The raw_input() function reads formatted input from the keyboard. When the user
enters a string (i.e) char array, it is stored in variable testString. Format
string %s is used in case of string which is an array of character types. Note
the '&' sign before testString is not needed, the value will be stored
starting from the base address. NOTE: Bold letters or words are Input and rest
are output statements.

Q-8 : ASCII Values I
ASCII - American
Standard Code for Information Interchange. Write a program to get a character
as input and print it's ASCII value. When a character is entered, the character
itself is not stored. Instead, a numeric value(ASCII value) is stored. And when
we displayed that value using "%c" text format, the entered character
is displayed. NOTE: Bold letters or words are Input and rest are output statements.

Q-9 : Sece
Dining
The catering staff in
the SECE mess are known for their good cooking skills as well as hospitality.
We all know that the dining table arrangement needs to be different for left
handed and right handed persons. So whenever any VIP guests come to SECE, they
would make the table arrangements based on whether they are left handed or
right handed. The mess is situated on the 15th floor of the hostel building.
SECE hostel building has superfast elevators to help to travel from one floor
to another. Each elevator has 2 doors, the front one and the rear one. If a
person enters the elevator through the front door, he goes out through the rear
door and vice-versa. The elevator has 2 rails numbered as 1 and 2. Rail 1 is
located to the left of the entrance to the front door (or correspondingly, to
the right of the entrance to the rear door). Rail 2 is located opposite it, to
the right of the entrance to the front door and to the left of the entrance to
the rear door. We know that each person holds on the rail with his/her
strongest hand. There is an IP camera in the elevator and based on the camera
output, the catering staff will be easily able to identify whether a guest is
left handed or right handed. They have decided to automate this task and they
asked the help of Image Processing Group. The Image Processing Group has
written a program to perform this task and the program will output the door through
which the person entered and the rail number which the person held. Based on
this input, write a program to determine whether a person is left handed or
right handed?
Input format:
The first input containing a string denotes “front”
or “rear”
The second input containing an integer denotes rail 1
or 2
Output format:
Print the string "Left Handed" or
"Right Handed"

Q-6 : Viva
on Odd Numbers
A maths teacher asks
her students to give 3 examples for positive odd numbers. When the student
specifies a correct answer, his/her score is incremented by 1. When the student
specifies a positive even number, his/her score is decremented by 0.5. When the
student specifies a negative number, he/she will not be given any more chances
to correct his or her mistake and his/her score will be decremented by 1. So a
student's turn comes to an end when he/she has correctly specified 3 positive
odd numbers or when the student has specified a negative number. Few students
didn't know the difference between odd numbers and even numbers and they made
many mistakes and so it was difficult for the teacher to maintain the scores.
The teacher asks for your help. Can you please help her by writing a program to
calculate the score? Input Format: Input consists of a list of integers. Output
Format: Output consists of a single line. The score needs to be displayed
correct to 1 decimal place. Refer sample output for details. [For this
exercise, don't worry about duplicate odd numbers. Even if the students
specifies the same odd number thrice, it is accepted].

Q-8 : Target
Practise
Drona normally trains
his disciples using a board which consists of concentric circles. When the
student correctly hits the center of the concentric circles, his score is 100.
The score gets reduced depending on where the students hits on the board. When
the student hits outside the board, his score is 0. Drona will not allow a
student to have his food unless he scores 100. Arjuna will always hit the target
in his first attempt and he will leave early. Others may take more turns to
reach the score of 100. Can you write a program to determine the number of
turns a disciple takes to reach the target score of 'n' ? Input Format: Input

Q-10 : Special number
Wil Wheaton who has filled in the shoes
of Professor Proton in the show Professor Proton Fun with Mathematics wanted
the kids to learn about Special number.(A 2-digit number is said to be a
special number if the sum of sum of its digits and the product of its digits is
equal to the number itself. For example, 19 is a special number. The digits in
19 are 1 and 9. The sum of the digits is 10 and the product of the digits is 9.
10+9 = 19.) Can you help Wil to write a Python program to find all special
numbers between 2 limits m and n(both inclusive). Assume that m and n are
2-digit numbers.
Input Format:
Input consists of 2 integers m and n.
Output Format:

Refer to sample output for the output format.
Sample Input 1:

30
Sample Output 1:
19
29
Explanation:
Between 11 and 30, 19 and 29 are the numbers whose
sum of digits and product of digits when added gives the same number itself.
Hence, the two outputs possible are 19 & 29.
Sample Output 1:
11
19
Sample Output 2:

ReplyDeletePython is a powerful and versatile programming language. It can be used to perform a wide variety of tasks, including counting frequency of items in a list. This task can be completed using Python's built-in functions or by writing custom code to loop through the list and increment counters. The approach you choose depends on the complexity of your data set and the requirements for accuracy.
ReplyDeleteTo count frequency of items in a list using Python, you need to understand how to iterate over the list and access its elements one at a time. You then need to define an empty dictionary that will store each element from your list as a key, with its corresponding value as the number of times it appears in the source data set. Finally, you must use either built-in functions or loops within your code to increment these values for each occurrence of an item in your source data set.
