I used to believe that unordered_map is better in time-complexity than map in C++. But today while I was doing a problem(Molly's Chemicals), I got time-limit exceeded. After a lot of guess-work(because I thought my solution was correct), I tried using a map instead of an unordered_...
An (unordered) pair {p,q} of distinct states in Qn∖{0,n−1} is colliding (or p collides with q) in Tn if there is a transformation t∈Tn such that 0t=p and rt=q for some r∈Qn∖{0,n−1}. A pair of states is focused by a transformation u of Qn if u maps both...

Following [18], we say that an (unordered) pair {p,q} of distinct states in QM is colliding (or p collides with q) in T(Dn) if there is a transformation t∈T(Dn) such that 0t=p and rt=q for some r∈QM. A pair of states is focused by a transformation u∈T(n) if u ...
This happens often, even when there is a significant difference in time complexity, such as O(N) and O(N^2). If you want to know where the time complexity of hashmap, especially the unordered_map of C++, has a big constant, check the following videos and links....
(directed) cycles. LetGbe a plane graph and letFbe the set of inner faces ofG. Anarea assignmentis a real-valued functionA:F→R+. We say that a drawingG′isA-realizing, ifG′is a straight-line drawing equivalent toGin which the area of eachf∈Fis exactlyA(f). IfGhas anA-realizing...
The question is whether that is different from the alternative, being bumped into least energy states by unordered impacts from their environments. Both styles of ordering may have pattern development consequences. I think it distinguishes two very distinctly different classes of order development, ...
[164]. Specified complexity usually lies closer to the noncompressible unordered end of the complexity spectrum than to the highly ordered end (Fig.4). Patterning usually results from the reuse of programming modules or words. But this is only secondary to choice contingency utilizing better ...
A little confusion on unordered map complexity Here, in solution 1, I used 3 unordered map and getting TLE but when I used 2 unordered map on solution 2 it gets AC. Why this happened while unordered map searches, inserts, and deletes elements in O(1)?
High-dimensional gene expression data provide a rich source of information because they capture the expression level of genes in dynamic states that reflect the biological functioning of a cell. For this reason, such data are suitable to reveal systems r
