Problem : Online Communities - Even Groups-2014 In a social network, online communities refer to the group of people with an interest towards the same topic. People connect with each other in a social network. A connection between Person  I  and Person  J  is represented as  C I J . When two persons belonging to different communities connect, the net effect is merger of both communities which I and J belonged to. We are only interested in finding out the communities with the member count being an even number. Your task is to find out those communities. Input Format: Input will consist of three parts, viz. 1. The total number of people on the social network  (N) 2.Queries  C I J , connect I and J Q 0 0 , print the number of communities with even member-count -1 will represent end of input. Output Format: For each query Q, output the number of communities with even member-count Constraints: 1<=N<=10^6 1<=I, J...

  [SOLVED]  By Parth Makadiya It's been a few months I'm using the GS3. Everything was working fine. Suddenly, yesterday, this fantastic quad-core beast refused to charge! I made so many attempts but all in vain   : Tried a different charger. Tried a different USB Cable. Tried charging it via PC/Laptop. Tried removing the battery, cooling everything down and then charging again. Blew inside the USB port. Rebooted several times. Done a factory reset (I know it wasn't a thing to be done.. but... ). What is the problem?! I've never dropped it or something like that! It's too important for me to have a phone! Won't send it to Samsung ever. I think people at XDA have more brains. The  only  connection to the internet at my home is my S3's GPRS. Wait a minute... if S3 isn't charging how am I posting and starting this thread? It charges.  ONLY 15% in 3 hours  when it's  Switched OFF  and it's charged...
