Solution:

Here, we have to pay attention to the point that the army band members and army contingent members have to march in the same number of columns and that the number of columns must be the maximum possible number.

The definition of HCF states – HCF is the highest number that can be divided exactly into each of two or more numbers. In other words, the HCF of two numbers is the highest number (maximum) that divides both numbers.

Thus, we have the find the HCF of the members in the army band and the army contingent.

HCF (616, 32) will give the maximum number of columns in which they can march. We use Euclid’s algorithm to find the H.C.F:

616 = (32 × 19) + 8

32 = (8 × 4) + 0

The HCF (616, 32) is 8.

Therefore, the maximum number of columns in which they can march is 8.

Strings

Python is a famous programming language and strings are very popular types in it. In python string literals are surrounded by single quotes or double quote. Example, “hello” or’hello’. The capitalize () method in python returns a copy of a string with only its first letter capitalized. Its syntax is as follows: str.capitalize(). The two parameters of center() method are fillchar and width. Fillchar is the filler character whereas width is the total width of the string. In python programming language, strings are arrays of bytes which represent Unicode characters

Computer software can be divided into two categories namely system software and application software. Internal operations are controlled by some software. Such software is called system software. Example, compilers, operating system, interpreters, etc. The software which helps to carry out a particular application is called application software. Example, MS Excel, MS Word, etc.

Types of the operating system:

• Single user OS – Allows only one person to use at a time. Also, only one program can be loaded and executed at a time.
• Multi-user OS – Two or more than two people can use at a time. Example, Windows, Linux, etc.
• Real-time OS – As soon as an input is given it will respond instantly. It is used in communication and flight control system.

Programming Methodology is an approach to analyze complicated problems by controlling the development process and planning software development. Before writing a program, programming methodology is used. Breaking a problem into sub-problems is called modular approach. Comments do not increase execution time. There are two types of comments.

• Single line comment – You are allowed to have a comment in short, up to one line.
• Multiple line comment – When you have a text that contains more than one line it is called multiple line comment.

Programming methodology is a framework used to plan, control and structure the process of developing an information system.

NCERT Solutions Class 11 Computer Science – Operators in Python is explained in this page in easy way to understand. You can learn Python in MYNCERT for learning programming and prepare for exams.

Types of operators used in python are arithmetic operators, assignment operators, bitwise operators, identity operators, comparison operators, membership operators, logical operators.

Various operators used are as follows:

• + Addition

Adds values on both sides of the operator

• – Subtraction

Left-hand operand is subtracted from the right-hand operand

• * Multiplication

Multiplies values on both sides of the operator

• / Division

The right-hand operand is divided by the left-hand operand

• ** Exponent

Performs exponential calculations

Comparison operators used in python are ==, !=, <>, >, <, >=, <=. To learn how to tackle questions asked on membership operators, logical operators, assignment operators, bitwise operators, identity operators, etc. study from the below-given solution.

The main memory or the primary memory of a computer is classified into RAM and ROM.

• RAM (Random access memory) – It communicates with the environment with the help of address selection lines, output and input lines. The electric charge is stored by dynamic RAM. Dynamic RAM is also called DRAM and it consists of a capacitor and transistor. Various designs of DRAM are SDRAM (Static DRAM), DDR DRAM (double data rate DRAM), EDO DRAM (extended data out DRAM), RDRAM (Rambus DRAM).
• ROM (Read Only Memory) – It cannot write but only read. Types of ROM are PROM (Programmable Read Only Memory), EPROM (Erasable Programmable Read Only Memory), EEPROM(Electrically Erasable PROM).

In this page we are explaining the NCERT Solutions Class 11 Computer Science – Lists, Dictionaries, and Tuples. Our subject matter experts made it easy for all the students to understand the concept.

Lists:

Lists are mutable and the values can be changed by the programmer. They are one of the powerful tools. One list can contain objects, integers, and strings as well. It can be used to implement queues and stacks. Once declared, they can be altered or modified.

Tuples:

Tuples are immutable and the values cannot be changed by the programmer. They are similar to lists but cannot be modified or changed once they are declared. They are easy to make. For example, the days of the week-

days = (‘Sunday’,’Monday’,’Tuesday’,’Wednesday’,’Thursday’,’Friday’,\
‘Saturday”)

The result is like this:

Index	Value
0	Sunday
1	Monday
2	Tuesday
3	Wednesday
4	Thursday
5	Friday
6	Saturday
