I you visited a node already , why you process the node again ? just add if(visited[node]==true) continue ; in 85 number lines . Thanks.
thanks

I take TLE in testcase 12. Is my logic wrong? Or I can optimize it a bit?
find a node which has lower cost to invent and process it . If cost is tie of two nodes , than consider the node which edge cost is lower to reach the node . My solution http://codeforces.me/contest/545/submission/11163248
Thank you a lot man. I solved it. You really helped me.
(Erase was so slow,so I did the sorting as you recommended).
