CODING QUESTION

Chess queen moves horizontally, vertically or diagonally to any number of cells. Given two different cells of the chessboard, determine whether a queen can go from the first cell to the second in one move.

The program receives the input of four numbers from 1 to 8, each specifying the column and row number, first two - for the first cell, and then the last two - for the second cell. The program should output YES if a queen can go from the first cell to the second in one move, or NO otherwise.

SOLUTION

x1=int(input())
y1=int(input())
x2=int(input())
y2=int(input())

if abs(x2-x1) == abs(y2-y1) or abs(x2-x1)==0 or abs(y2-y1)==0:
    print('YES')
else:
    print('NO')
