Remove components sort, Kosaraju should be O(n)

[chubakueno]

sort(component.begin(), component.end()) is linearithmic, which breaks the expected linear complexity of Kosaraju. Line is also superfluous and unnecesary.

I'm shocked that someone rewrote this and made the code worse... It was correct before it was updated 2 months ago. You're right that there's no need to sort.

Sorry, I didn't think about that. The line should indeed be removed, but this sentence should then also be modified (e.g. by removing the word 'sorted'):

When building the adjacency list of the condensation graph, we select the root of each component as the first vertex in its sorted list of vertices (this is an arbitrary choice).

Thanks for catching this mistake!

@el-sambal suggestion taken, updated the description!
