HAWKEYE AND FLOODFILL - Practice Problem from HackerEarth and solution using python 2.7.6

Problem Statement:

Hawkeye is a MARVEL character who has a perfect aim in archery. Its almost impossible for him to miss his aim. As you are the head of technical team at MARVEL , you have been assigned a very critical task. During practice hawkeye uses a square archery practice board. For our convenience we will assume it to be a N * N matrix. He shoots an arrow at position i,j with power P. Now power reduces by 1 as we move away from position i,j . Your task is to show the graph representing the impact of the arrow on the practice board.

INPUT FORMAT
First line of input contains a single integer N denoting the size of the practice board.
Second line contains 3 integers i,j denoting position at which arrow was shot and p denoting the power used to shoot the arrow.

OUTPUT FORMAT
Output a 2D matrix representing the impact on the practice board.

CONSTRAINS
1<=N<=1000
0<=i,j 0<=p<=10⁹

Note:- The matrix is zero indexed matrix ie: first element will be at 0,0

Programming using python 2.7.6:

Size_of_Board = int(raw_input())

Pos1,Pos2,Power = map(int,raw_input().split())

def get_max(x1,y1,x2,y2):

    x = x1 - x2

    y = y1 - y2

    return max(abs(x),abs(y))

def get_difference_value(power,maxval):

    if (power - maxval) > 0:

        return (power - maxval)

    else:

        return 0

for a in range(Size_of_Board):

    for b in range(Size_of_Board):       

        print get_difference_value(Power,get_max(Pos1,Pos2,a,b)),       

    print
