Reverse the given string word wise. That is, the last word in given string should come at 1st place, last second word at 2nd place and so on. Individual words should remain as it is.

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.

We are suffering from the Second wave of Covid-19. The Government is trying to increase its vaccination drives. Ninja wants to help the Government to plan an effective method to help increase vaccination following safety measures. Time is running out. Can you help the nation?

You are given two positive integers: ‘n,’ ‘maxVaccines’ denoting the number of days for which this vaccination drive will go on and the total number of vaccines available for the drive, respectively. You have to find the number of vaccines administered each day. You are also given a number ‘dayNumber,’ and we are interested to know the maximum number of vaccines that can be administered on ‘dayNumber’ th day.

The rules of the vaccination drive :

1. There should be a positive number of vaccines administered each day during the vaccination drive.

2. The absolute difference between the number of vaccines in two consecutive days should not exceed 1.

3. The sum of all the elements of the vaccines array does not exceed maxVaccines, that is, you cannot administer more vaccines than what is provided to you.

4. Vaccines administered on ‘dayNumber’ th day should be maximized.
