A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. 187 more words

Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list.

For example,

Given `1->2->3->3->4->4->5`

, return… 129 more words

Given a linked list, reverse the nodes of a linked list k at a time and return its modified list.

If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is. 194 more words

The connection tracking entry (conntrack entry) looks like this:

udp 17 170 src=192.168.1.2 dst=192.168.1.5 sport=137 dport=1025 src=192.168.1.5 dst=192.168.1.2 sport=1025 dport=137 use=1
