Write a program to calculate the total bill tax amount for a list of billing amounts passed as an array of long integers.Up to the amount of 1000, there is no tax applicable, subsequently, a flat tax of 10% is applicable for the remaining amount as per the tax rate.Input -  51000 2000 3000 4000 5000Output- 1000

You are given a paragraph that may have letters both in lowercase and uppercase, spaces, and punctuation. You have also given a list of banned words. Now your task is to find the most frequent word which is not in the list of banned words. There will always be a solution, and the solution will be unique.

While comparing words, you can ignore whether the letter is lowercase or uppercase. For example, ‘AsK’ and ‘aSK’ are the same. The words will always contain only alphabets or we can say words will be separated by spaces or punctuation. The answer will be in uppercase letters.

The words in the banned list will always be in upper letters and free from punctuation and spaces.

For example :

Paragraph = ‘It's a square SqUare. It's a FLAT flat.’ 
Banned =[FLAT, IT, S]. 
So we can see these words [IT, S, SQUARE, FLAT ]  are most frequent.
Now we will look at to banned list and we can see 3 of the words are banned.
So we have a unique answer SQUARE which has a frequency of 2 and not on the banned list.

Given an n x n matrix mat[n][n] of integers, find the maximum value of mat[c][d] – mat[a][b] over all choices of indexes such that both c > a and d > b.

Example:-

1 2 3 4 
5 6 7 8
1 9 2 3

In this example, the maximum value is 8 (mat[2][1]-mat[0][0]).
