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.

You are given a grid of size N*M. There are two types of people, type ‘A’ and type ‘B’ . You are also given the number of people of each type say ‘countA’ is the number of ‘A’ type persons and ‘countB’ is the number of ‘B’ type of persons. The satisfaction of a particular type of person can increase or decrease as follows :

The initial satisfaction of a person of type A is 80. It decreases by 20 for each neighbor.

The initial satisfaction of a person of type B is 50. It increases by 10 for each neighbor.

Your task is to determine the maximum possible grid satisfaction.

Note:

You may choose exactly how many people you want to be present in the grid.

The total number of people of type ‘A’ living in the grid can be less than ‘countA’ but cannot exceed ‘countA’. Similarly, total number of people of type ‘B’ living in the grid can be less than ‘countB’ but cannot exceed ‘countB’

A person can live in only one cell.

Not more than one person can live in a cell.

Two cells are said to be neighbors if the cells are adjacent and share a boundary.

You are given a string 's' that represents a Roman number. Convert the Roman number to an integer and return it.

Roman numerals are represented by seven different symbols: I, V, X, L, C, D, and M.

Table of values:

Symbol       Value
I             1
V             5
X             10
L             50
C             100
D             500
M             1000

For example:

3 is written as III in Roman numeral, just three ones added together. 13 is written as XIII, which is simply X + III. The number 25 is written as XXV, which is XX + V 

Given a table find highest the salary of top 3 employees

Interviewer gave some scenario based questions like if you are assigned to a task and that task need to be completed in 2 days but it will its actual time was 3 days, what will you do in that case
