convert ten digits into a string:

rules for conversion:

separate the number into a set of four-three-three

Two consecutive numbers: double

Three consecutive numbers: triple

Four consecutive numbers: quadruple

sample input:9966777819

output should be:double nine double six triple seven eight one nine

Sample input2: 9999

Output should be: quadruple nine

Sample input3: 88

Output should be: double eight

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source.

Nested lists

The “*” operator

List slices

The “+=” operator

A list filter

A list operation that is legal but does the "wrong" thing, not what the programmer expects

Provide the Python code and output for your program and all your examples

Construct a class named “Book” that assigns title, author and format as initial values.

Create a class named “Library” that extends “Book” and assigns available as initial value, a method named updateAvailability that updates availability of the book, and a method named “str” that returns the string representation of the class.

Write an “abstract” class, Box, and use it to define some methods which any box object should have: add, for adding any number of items to the box, empty, for taking all the items out of the box and returning them as a list, and count, for counting the items which are currently in the box. Write a simple Item class which has a name attribute and a value attribute – you can assume that all the items you will use will be Item objects. Now write two subclasses of Box which use different underlying collections to store items: ListBox should use a list, and DictBox should use a dict.

Write an algorithm to find the total number of units of memory allocated deallocated by the server 1 after preprocessing all the requests

given a number of days(N) as input, write a programme to convert N to years(Y),weeks(W)and days(D)

if the input is :

4 4

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

then output should be:- 1 2 3 4 8 7 6 5 9 10 11 12 16 15 14 13

Given a MxN matrix,write a program to print all Anti-Diagonals elements of matrix

Input

The first line of input will contain a M, N values separated by space.

The second line will contain matrix A of dimensions MxN.

Output

The output should contain anti-diagonal elements separated by a line.

Explanation

For example, if M = 2, N = 3

Matrix A:

1 5 5

2 7 8

Output:

1

5 2

5 7

8
