AnswersHi there,
- xyz June 08, 2019 in United States
I'm using a Debian 8 system running Strongswan 5.2 to connect to Cloud VPN, but I'm seeing a large amount of packets being dropped. I'm not sure if the problem is on my side, so I need help debugging from the Google side.

AnswersHi,
- xyz June 08, 2019 in United States
My virtual machine is talking to our on-premise Hadoop cluster and we have observed connections dropped by the VM after approximately 15 minutes after being established. We have tried tweaking our cluster and the VPN, but it did not work. We have also disabled any firewall or NAT: our cluster is connected directly to the Internet. We ran a TCP packet capture on one of our routers and we do see the following:
408 7.963058 178.124.133.65 172.16.72.34 TCP 66 http > 42867 [FIN, ACK] Seq=312 Ack=11 Win=14592 Len=0 TSval=3673141343 TSecr=234006479

Please help, this is a fault in your network, I need a solution ASAP!

AnswersGenerate n numbers in ascending order which are having given k factors.
- rahulkumar5july July 06, 2015 in United States
Eg. {2,3,4,7}
then it generate number like this.
2,3,4,6,7,8,9,10 .....
My approach is that make a min heap with given k factors.In every iteration extract one element from heap to output and put next multiplication of outputed number to min heap.
For duplicate numbers we can take an array or hashmap for denoted that number is taken or not.
My question is,How can we handle duplication without extra space.
Or any other good approach for this question ?| Report Duplicate | Flag | PURGE

AnswersWrite a prog in any language you are comfortable, which takes 2 strings as an input and then finds the first occurrence of the first string in the second string. The function should return the index in the second string where the match was found.
- Jey January 24, 2014 in India
Tip : The basic algorithm here is to iterate through the second string and when the char matches the first char in the 1st string., check if subsequent substring is a match, and return if it is.| Report Duplicate | Flag | PURGE
