#include <stdio.h>
int main(int argc, char *argv[]) {

int a, b,c, d, x, y, k;
  if(a<=x&&x<=b){
    if(c<=y&&y<=d){
  if(scanf("%d", &a)< 10000000000){
     if(scanf("%d", &b)>1000000000){
        if(scanf("%d", &c)<100000000){
           if(scanf("%d", &d)>1000000000){
 
  
	

	if(a>0&&c>0){
    k=b*d;
    }
	if(a<0&&c>0){
    k=b*c;
    }
  	if(a>0&&c<0){
    k=a*d;
    }
  else {
  k = b*d;
  }
  printf("%d",k);
  }
        }
