Revisited Disjoint Set Union by Abhinav Sharma | HackerEarth
- “Notice that we used the function call findParent( i ) to find the parent of the ith node, instead of directly looking at parent[ i ]. The reason for this is: The parent of a node is not changed as soon as its affiliation to a connected component is changed. We postpone this to when we actually need to find the parent of the node. Doing this avoids many useless operations. So, parent[ i ] may not contain the updated value of the connected component that i belongs to. That’s why it’s important that we use findParent( i ) instead of being lazy and taking the value directly from parent[ i ]”
- I skipped the calculation of its time complexity for now..

I'm reading Alain's propos, but they are very boring… hard to understand what he is trying to say.
