I am new to python and practising questions side by side. I came across a problem on snakify.org and solved using below code. Can this code be more simplified? Problem statement: Chess king moves horizontally, vertically or diagonally to any adjacent cell. Given two different cells of the chessboard, determine whether a king 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 king can go from the first cell to the second in one move, or NO otherwise. I tried this solution on various possible sets and works fine but still, wonder if the lines of code could be reduced? x1 = int(input()) y1 = int(input()) x2 = int(input()) y2 = int(input()) def xcell(x1,x2): x=0 if x1 -x2 > 0: x = x1 - x2 elif x1-x2 < 0: x = x2-x1 else: x return x def ycell(y1,y2): y=0 if y1 -y2 >= 0: y = y1 - y2 elif y1-y2 < 0: y = y2-y1 else: y return y if ((xcell(x1,x2) == 1) & (ycell(y1,y2) == 0))or ((xcell(x1,x2) == 0) (ycell(y1,y2) == 1))or((xcell(x1,x2) == 1) & (ycell(y1,y2) == 1)): print("YES") else: print("NO") The expected output is YES if the user provides input 4,4,5,4 Continue reading...
