algorithm - Graph is connected or not ! in c language for ford fulkersion -

-

// created part of ford fulkersion algorithm

#include<stdio.h> #include<conio.h>  void main() {     int v,i,e,ch[20],sv[20],count=0,s,j;     clrscr();     printf("enter no of vertices :");     scanf("%d",&v);     for(i=1;i<=v;i++)     {         printf("enter vertices %d",i);         scanf("%d",&sv[i]);     }     printf("enter starting node : ");     scanf("%d",&s);

//problem in below loop(logic not working ) if 1 have solution please !

    for(i=s;i<=v-1;i++)     {         for(j=i+1;j<=v;j++)         {             printf("conn betn %d , %d",i,j);             scanf("%d",&ch[i]);             if(ch[i]!=1)             {                 break;             }             else if(ch[i]==1)             {                 count++;             }         }     }

//----------------------------------------------------------

if(count>=v) {     printf("graph connected"); } else {     printf("graph disconnected"); } getch();

}

your algorithm wrong. assuming if have @ least v edges, graph connected. if have graph this, 6 nodes , 6 edges, still not connected:

you naively expect work: import pytz datetime import datetime def tz_datetime_from_timestamp(timestamp): """convert timestamp datetime """ tz = pytz.timezone('australia/perth') server_time = datetime.utcnow() delta = tz.utcoffset(server_time) value = datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz) return value + delta print tz_datetime_from_timestamp(1416387060) and convert timestamp 1416387060 wed nov 19 16:51:00 2014 gmt+8:00. ...but not. prints: 2014-11-19 16:51:00+07:43 the timezone of australia/perth not gmt+7:43. it gmt+8:00. unequivocally stated on australian government website http://www.australia.gov.au/about-australia/our-country/time : awst equal coordinated universal time plus 8 hours (utc +8). so, heck pytz pulling 7.43 from? well, turns out pytz pulls data http://www.iana.org/time-zones time zone database, , database states: # western australia # # rule name type in on @...
