You will be given a square matrix of N rows and N columns (1 <= N <= 1000) containing positive and negative integers with absolute value not larger than 1000. You are required to compute the greatest sum achievable by walking a path, starting at any cell of the matrix and always moving downwards or rightwards. Additionally, you have to report the number of times that value is achievable. N will be in the first line of the input. N lines follow with N integers each. You should output a single line with two integers separated by a single blank space: first one is the greatest sum, second one is the number of times this value can be reached.

Case 1:

For the input provided as follows:

5
3 1 -2 1 1
-6 -1 4 -1 -4
1 1 1 1 1
2 2 2 2 2
1 1 1 1 1

Output of the program will be:

Number in python

2020-04-20T13:54:00.002+05:30

If you’ve done any programming or scripting in the past, some of the object types in
Table 4-1 will probably seem familiar. Even if you haven’t, numbers are fairly straight-
forward. Python’s core objects set includes the usual suspects: integers that have no
fractional part, floating-point numbers that do, and more exotic types—complex
numbers with imaginary parts, decimals with fixed precision, rationals with numerator and
denominator, and full-featured sets. Built-in numbers are enough to represent most
numeric quantities—from your age to your bank balance—but more types are available
as third-party add-ons.
Although it offers some fancier options, Python’s basic number types are, well, basic.
Numbers in Python support the normal mathematical operations. For instance, the
plus sign ( + ) performs addition, a star ( * ) is used for multiplication, and two stars ( ** )
are used for exponentiation:
>>> 123 + 222
# Integer addition
345
>>> 1.5 * 4
# Floating-point multiplication
6.0
>>> 2 ** 100
# 2 to the power 100, again
1267650600228229401496703205376
Notice the last result here: Python 3.X’s integer type automatically provides extra
precision for large numbers like this when needed (in 2.X, a separate long integer type
handles numbers too large for the normal integer type in similar ways). You can, for
instance, compute 2 to the power 1,000,000 as an integer in Python, but you probably
shouldn’t try to print the result—with more than 300,000 digits, you may be waiting
awhile!
>>> len(str(2 ** 1000000))
301030
# How many digits in a really BIG number?
This nested-call form works from inside out—first converting the ** result’s number
to a string of digits with the built-in str function, and then getting the length of the
resulting string with len . The end result is the number of digits. str and len work on
many object types; more on both as we move along.
On Pythons prior to 2.7 and 3.1, once you start experimenting with floating-point
numbers, you’re likely to stumble across something that may look a bit odd at first
glance:
# repr: as code (Pythons < 2.7 and 3.1)
>>> 3.1415 * 2
6.2830000000000004
>>> print(3.1415 * 2)
6.283
# str: user-friendly
The first result isn’t a bug; it’s a display issue. It turns out that there are two ways to
print every object in Python—with full precision (as in the first result shown here), and
in a user-friendly form (as in the second). Formally, the first form is known as an object’s
as-code repr , and the second is its user-friendly str . In older Pythons, the floating-point
repr sometimes displays more precision than you might expect. The difference can also
matter when we step up to using classes. For now, if something looks odd, try showing
it with a print built-in function call statement.
Better yet, upgrade to Python 2.7 and the latest 3.X, where floating-point numbers
display themselves more intelligently, usually with fewer extraneous digits—since this
book is based on Pythons 2.7 and 3.3, this is the display form I’ll be showing throughout
this book for floating-point numbers:
# repr: as code (Pythons >= 2.7 and 3.1)
>>> 3.1415 * 2
6.283
Besides expressions, there are a handful of useful numeric modules that ship with
Python—modules are just packages of additional tools that we import to use:
>>> import math
>>> math.pi
3.141592653589793
>>> math.sqrt(85)
9.219544457292887
The math module contains more advanced numeric tools as functions, while the ran
dom module performs random-number generation and random selections (here, from a
Python list coded in square brackets—an ordered collection of other objects to be in-
troduced later in this chapter):
>>> import random
>>> random.random()
0.7082048489415967
>>> random.choice([1, 2, 3, 4])

Constructor Concept(Python)

2020-04-19T23:38:00.000+05:30

Constructor is a special method in python.
The name of the constructor should be __init__(self)
Constructor will be executed automatically at the time of object creation.
The main purpose of constructor is to declare and initialize instance variables.
Per object constructor will be exeucted only once.
Constructor can take atleast one argument(atleast self)
Constructor is optional and if we are not providing any constructor then python will provide default constructor.

Example:

def __init__(self,name,rollno,marks):
self.name=name
self.rollno=rollno
self.marks=marks
Program to demonistrate Constructor will execute only once per Object:

class Test:

what is class?(python) with example

2020-04-18T12:10:00.004+05:30

In Python every thing is an object. To create objects we required some Model or Plan
or Blue print, which is nothing but class.
We can write a class to represent properties (attributes) and actions (behaviour) of object.
Properties can be represented by variables Actions can be represented by Methods.
Hence class contains both variables and methods.

How to define a Class?

We can define a class by using class keyword.

Syntax:

class className:

''' documenttation string '''

variables:instance variables,static and local variables

methods: instance methods,static methods,class methods

Documentation string represents description of the class. Within the class doc string is

always optional. We can get doc string by using the following 2 ways.

1) print(classname.__doc__)

2) help(classname)

Example:

1) class Student:

''''' This is student class with required data'''

3) print(Student.__doc__)

4) help(Student)

Basic concept of object oriented programming c++

2020-03-31T21:04:00.004+05:30

1.object

2.class

3.data abstraction

4.data encapulation

5.inherentance

6.polymorphisims

7.dynamic binding

8.message passing

1.object :-
object are basic run time antities. eg- a table a person ,a place ,a bankaccount .
The object required a memory space to store in memory because object space contain data one object required a memory space to store in memory because object contain data one object may commiuncate another object by sending or receiving message to one another.
eg- bankaccounter
we can say that real life entity in real world.

2.class:-
we just mainstion that object contain data and code two manupalate that data.
The entire set of data and code of an object can be made a user define datatype with the help of class infact object are variable of type class.
one a class has define we can create any number of object belonging to the class
eg- mango,apple,orange are member of class fruit.
classes are user define datatype and behave like building datatype.

3.data abstraction :-
data abstraction refer to act of represeentating the ensical feature without including background detals. on explaning classes use the concept of abstraction
eg- following are different list of abstract attibutes, size ,weight , cost etc
and function operates on this attributes called as data member and function called as member function

4. data encapulation :-
rapping of the data and function into a single units is called data encapulation .
eg - CPU
dataencapulation is most striking feature of the class.
The data is not accientable to the outside world .
The data is acciable to only function which are rapped in the class .

5.inheritance :-
inheritance is the process by which object of one class aqurired the properties of object of another class .
inheritance is the hirachical classfication
i)single inheritance
ii)multiple inheritance
iii)haricical inheritance
iv)multilevel inheritance
v)hybrid inheritance

Arithmetic operation for given number

2020-03-31T10:13:00.002+05:30

Q. write a python program arithmetics operation for the given number.
consider the two number num1=20 num2=10

Ans:
num1=20
num2=10
num3=num1+num2
print("The addition of two number is=",num3)
num4=num1-num2
print("The substraction of two number is",num4)
num5=num1*num2
print("The multiplication of two number is",num5)
num6=num1/num2
print("The division of two number is",num6)

Output
The addition of two number is=30

The substraction of two number is=10

The multiplication of two number is=200

The division of two number is=2

Addition of two number using python

2020-03-31T09:47:00.002+05:30

Q. program to write the addition of two number using python programming
The given number is num1=10 & num2=20.
Ans:

num1=10 #first given number
num2=20 #second given number
num3=num1+num2
print("The addition of two number is=",num3)

output:
The addition of two number is=30

Feature of object oriented programming (C++)

2020-03-31T09:33:00.003+05:30

1.The program divided into object.
2.Object oriented follows bottom of opproch.
3.In object oriented programming data is hidden cannot access outside function.
4.New data function can be easily added in object oriented programming.
5.function and data are tight together single unit called object.

introduction of c++

Introduction in c++

2020-03-31T09:25:00.000+05:30

1.c++ is a object oriented programming language.
2.The need of invention of oriented programming language is to remove some of drawbacks form proceture oriented programming language .
3.In object oriented programming language more security is given by Data.
4.Data is accessible only the function which are tight to the particular object.
