Type the expressions below in python interactively, and try to explain what's happening in each case: a. 2 ** 16 2 / 5, 2 / 5.0 b. "spam" + "eggs" S = "ham" "eggs " + S S * 5 S[:0] "green %s and %s" % ("eggs", S) c. ('x',) [0] ('x', 'y') [1] d. L = [1,2,3] + [4,5,6] L, L[:], L[:0], L[-2], L[-2:] ([1,2,3] + [4,5,6]) [2:4] [L[2], L[3]] L.reverse(); L L.sort(); L L.index(4)

1.Use a for loop and the list append method to generate the powers of 2 to produce the following result [1, 2, 4, 8, 16, 32, 64, 128]

2.Write a for loop that prints a dictionary's items in sorted (ascending) order

Write a python script that get Room No, Room Rent per day, Number of days stayed in and extra charges (breakfast, lunch, and dinner) and display total bill to customer.

Ordered Matrix

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.

Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.

Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.

Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3
30 10 2
5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

1 2 3
5 10 11
15 20 30

Sample Input 1

3 3

1 20 3

30 10 2

Add two polynomials

Given two polynomials A and B, write a program that adds the given two polynomials A and B

Output

Print the addition of polynomials A and B.

If the degree of polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.

For term Cix^Pi, if the coefficient of the term Ci is 1, simply print x^Pi instead of 1x^Pi.Explanation

Sample Input 1:-

Sample Output 1:-

12x^8 - x^7 - 20x^6 - 72x^5 - 39x^4 + 118x^3 + 34x^2 + 43x - 120

Note :- Need Space between - and + operators

Sample Input 2:-

Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

Input:-

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).

Output:-

The output should be a single line containing the secret message. All characters in the output should be in lower case.

For Example -

Input 1:-

python

Output 1:-

16-25-20-8-15-14

Input 2:-

Foundations

Output 2:-

6-15-21-14-4-1-20-9-15-14-19

Input 3:-

python learning

Output 3:-

16-25-20-8-15-14 12-5-1-18-14-9-14-7

When we give three Inputs one by one they can give exact three Outputs must be come when code can be executed
