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

Sample Output 2

4

a = [int(i) for i in input("Enter list of numbers: ").split()]

Write this assignment using data classes 

1 Create a class Person a. Initialize a class Person with FirstName, LastName, Age, Address, and Contact Number.

2. Create a class Employee 

a. Employee is a Person so Employee is a child class of Person class. Employee class constructor/__init__ method will contain all the attributes of Person class and Employee class own attributes which are EmployeeID, OrganizationName and Position.

3. Create a class CommissionEmployee

a. CommissionEmployee is a child class of Employee class. It should inherit all the attributes of

Employee class and its own attribute which is commissionRate

b. Create a method called calculateCommission, which should take input of gross sale from the

user and based on the commission rate calculate the totalEarning.

c. Create a method called displayData which should display the FirstName, LastName, Age,

Address, ContactNumber, EmployeeID, OrganizationName, Position, commissionRate and

totalEarning. 

Write a program that use dictionaries to build tables. Complete a method that

receives 2 parameters. The first parameter states how many entries are in the dictionary and the second

number represents the multiplier for each entry.

Ex:

Input: 10, 5

Output: {1: 5, 2: 10, 3: 15, 4: 20, 5: 25, 6: 30, 7: 35, 8: 40, 9: 45}

printing sentence in decreasing order based on number

example

input= It took 13days 14nights to reach delhi by walk

output=It took 14days 13nights to reach delhi by walk (as decreasing order is 14,13 just numbers got replaced not word)

3. If speed > speed limit and helmet is not worn, then fine = Rs 5000;

4. If speed <= speed limit and helmet is worn, then print 'No Fine'

Output Format

Fine: Rs 1000

(or)

No Fine
