Rotate Matrix Rings

Given a matrix of order M*N and a value K, write a program to rotate each ring of the matrix clockwise by K elements. If in any ring has less than or equal to K elements, then don’t rotate that ring

M, N = input().split()
M, N = int(M), int(N)
matrix = []
for _ in range(M):
	row = [int(x) for x in input().split()]
	matrix.append(row)
K = int(input())
values = matrix[0][:-1] + [x[-1] for x in matrix][:-1] + matrix[-1][::-1][:-1] + [x[0] for x in matrix][::-1][:-1]
values = values[-K:] + values[:-K]
output = matrix
idxs = [(0, j) for j in range(N)][:-1] + [(i, N - 1) for i in range(M)][:-1] + [(M - 1, j) for j in range(N)][::-1][:-1] + [(i, 0) for i in range(M)][::-1][:-1]
idx = 0
for i, j in idxs:
	output[i][j] = values[idx]
	idx += 1
for i in output:
  pass
  print(i)

Input:

4 4

1 2 3 4 

5 6 7 8 

9 10 11 12 

13 14 15 16 

3

Output:

[13, 9, 5, 1]

[14, 6, 7, 2]

[15, 10, 11, 3]

[16, 12, 8, 4]

Here the inner ring is not rotating the given times sir

Write a function even_int that consumes an integer and produces "Even" if it is even and

"Odd" otherwise. You should use if and else for the two cases.

Write a function greeting that consumes a string of length at least three and produces "Hello"

if the first three characters are "Hi!" and produces "Bye" otherwise.

Write a function bigger that consumes two numbers and produces the maximum of the two numbers.

Area of Square

Given an MxN matrix filled with

X's and O's, find the largest square containing only X's and return its area. If there are no Xs in the entire matrix print 0.Input

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

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

Output

The output should be a single line containing the area of the maximum square.

Explanation

For example, if the given M, N and elements of matrix are as the following

4 5

X O X O O

X O X X X

X X O X X

X O O X O

The matrix from indices (1, 3) to (2, 4) has the maximum square with

X. So the output should be the area of the maximum rectangle with X, which is 4.

Sample Input 1

4 5

X O X O O

X O X X X

X X O X X

X O O X O

Sample Output 1

4

Sample Input 2

3 3

O X X

O X X

O O O

Number to English Words

Write a program to convert a non-negative integer

N to its English words representation.Input

The input will be a single line containing an integer

N. Note: The input number will not be greater than 10¹⁰.Output

The output should be a single line containing the representation of the English words of number

N. See the sample input and output for the English words of numbers in places.Explanation

For example, if the given number is 123, your code should print the English words representation, which is

One Hundred Twenty Three

Sample Input 1

123

Sample Output 1

One Hundred Twenty Three

Sample Input 2

10005

Sample Output 2

Ten Thousand Five

Sample Input 3

1234567891

Sample Output 3

One Billion Two Hundred Thirty Four Million Five Hundred Sixty Seven Thousand Eight Hundred Ninety One

for this question you have answered like:

but we are getting "ModuleNotFoundError: No module named 'num2words'"

import num2words
print(num2words.num2words(input()))

Area of Rectangle

Given an MxN matrix filled with

X's and O's, find the largest rectangle containing only X's and return its area. If there are no Xs in the entire matrix print 0.
Input

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

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

Output

The output should be a single line containing the area of the maximum rectangle.

Explanation

For example, if the given M, N and elements of matrix are as the following

4 5

X O X O O

X O X X X

X X X X X

X O O X O

The matrix from indices (1, 2) to (2, 4) has the maximum rectangle with

X. So the output should be the area of the maximum rectangle with X, which is 6.

Sample Input 1

4 5

X O X O O

X O X X X

X X X X X

X O O X O

Sample Output 1

6

Sample Input 2

3 3

O X X

O X X

O O O

Smaller Scores

A group of people(

P) are playing an online game. Their scores are stored in order of their entry time in S. Each integer S[i] corresponds to score of person Pi.For each person

Pi you have to report the number of people who played after person and scored less than the person.
Input

The first line contains a single integer

N. The second line contains N space-separated integers representing score S[i] of person Pi.
Output

Output should contain

N space-separated integers representing the number of people who played after person and scored less than the person.
Explanation

Given

S = 13 12 11Score of

P1 is 13. Score of P2 is 12. Score of P3 is 11.The number of people who played after

P1 and scored less than 13 is 2(12, 11). The number of people who played after P2 and scored less than 12 is 1(11). The number of people who played after P3 and scored less than 11 is 0.The output is

2 1 0.

Sample Input 1

3

13 12 11

Sample Output 1

2 1 0

Sample Input 2

4

4 3 5 2

Sample Output 2

2 1 1 0

# Write a function good_string that consumes a string, produces True if the first character is a 

# letter and the second character is either a digit or a blank space and produces False 

# otherwise
