back to boardPlease have a look at this - i got Comp.ERror not less than 10 times Hi! Here is my source - I compiled it on Visual C++ and it is OK - but here got "compilation Error". Could anyone explain me why??? #include <stdio.h> long x1,x2,y1,y2,ymin,ymax,n,i,posy,disttt; void main() { bool boo; boo=false; scanf("%ld",&n); scanf("%ld%ld%ld%ld",&x1,&y1,&x2,&y2); disttt=0; posy=1; ymin=y1; ymax=y2; for(i=1;i<n;i++) { scanf("%ld%ld%ld%ld",&x1,&y1,&x2,&y2); if(y1>=ymax-1||y2<=ymin+1) { printf("-1\n"); boo=true;; } if (posy<=y1) { disttt+=(y1+1-posy); posy=y1+1; } else if (posy>=y2) { disttt+=posy-y2+1; posy=y2-1; } ymin=y1; ymax=y2; } disttt+=x2-2; if (posy>y2-1) disttt+=posy+1-y2; else if(posy<y2-1) disttt+=y2-1-posy; if (boo==false) printf("%ld\n",disttt); } Thanks! Re: Please have a look at this - i got Comp.ERror not less than 10 times Try replacing y1 with y1_ and y2 with y2_. You will get accepted. The same thing happened to me. Re: Please have a look at this - i got Comp.ERror not less than 10 times Do not use bool,the compiler may not support this who can tell me what the difference is I think my code is right,but it was getting wa wa all the time. So I started to change it. I saw the code above,so I changed mine more and more like that. But a surprising thing ,my code is even equal to the code above, but it got accepted,but my still wa. I wonder.............. my code #include<iostream> #include<string> #include<memory> using namespace std; int main(void) { long n; cin>>n; long nowy=1,i,maxy,miny,x1,y1,x2,y2; long dist=0; cin>>x1>>miny>>x2>>maxy; bool ok=true; for(i=1;i<n;++i){ cin>>x1>>y1>>x2>>y2; if(y1>=maxy-1||y2<=miny+1){ ok=false; break; } if(y1>=nowy){ dist+=y1+1-nowy; nowy=y1+1; } else if(y2<=nowy){ dist+=nowy-y2+1; nowy=y2-1; } miny=y1; maxy=y2; } if(ok){ dist+=x2-2; //dist+=abs(y2-1-nowy); if(nowy>y2-1)dist+=nowy+1-y2; else if(nowy<y2-1)dist+=y2-1-nowy; cout<<dist<<endl; } else cout<<"-1"<<endl; return 0; } Re: Please have a look at this - i got Comp.ERror not less than 10 times Posted by cpc 15 Jun 2009 15:21 Now this code get AC. |
