这样都超时,我实在精简不了了#include <stdio.h>
#include <math.h>
void main()
{
int x,y,m,n,L;
scanf("%d %d %d %d %d",&x,&y,&m,&n,&L);
if(m==n){
printf("Impossible\n");
}
else{
if(m>n){
for(int k=1;;k++){
if(((m-n)*k-(y-x))%L==0){
printf("%d\n",k);
break;
}
}
}
else{
for(int k=1;;k++){
if(((n-m)*k+(y-x))%L==0){
printf("%d\n",k);
break;
}
}
}
}
}
