Solution in C++ (GCC 9.2.1) (judge verdict: Wrong Answer)

#include <stdio.h>
int max(int x,int y){
    if(x>=y)return x;
    return y;
}
int main(){
  int a[4];
  for(int i=0;i<4;i++){
      scanf("%d",&a[i]);
  }
  
  int temp[0];
  temp[0]=a[0]*a[2];
  temp[0]=max(temp[0],a[0]*a[3]);
  temp[0]=max(temp[0],a[1]*a[2]);
  temp[0]=max(temp[0],a[1]*a[3]);
  
  printf("%d",temp[0]);
 
  
   
    return 0;
}
