#include<stdio.h>
#include<math.h>

int fun(int n, int m, int p, int q){
	if(n==p||m==q||abs(n-p)==abs(m-q))
		return 1;
	else return 0;
}

void main(){
	int a[10][10], b[3], d[3], i, j, k, l, real, s=10, t=10;
	char c[3];

	for(i=1;i<=8;i++){
		for(j=1;j<=8;j++){
			a[i][j]=0;
		}
	}
	scanf(" %c%d %c%d %c%d", &c[0], &b[0], &c[1], &b[1], &c[2], &b[2]);
