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

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

(Reusability using inheritance)

The postage for ordinary post is Rs. 2.00 for the first 15 grams and Rs. 1.00 for each additional 10 grams. Write a C++ program to calculate the charge of postage for a post weighting N grams. Read the weights of N packets and display the total amount of postage using multiple inheritance.

* Base class-1: Member variables are name, source and destination.

* Base class-2: Member variables are no. of packets and weight.

* Derived class: Member functions display(), displays the name, source, destination, total weight and total amount.
