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

I really don't mean to bother anyone, this has just been annoying me for a good amount of time. The problem is835G. I seem to have a workingsolutionbut it's timing out at test 38. I thought my solution worked in O(n) but it clearly either doesn't or something else is very wro...
Let m be a map of S into S‾, and let D be a set of duos. We denote by m(D)={(m(i),m(i+1))|(i,i+1)∈D} the image of D under m. We say that m preserves D if m preserves each duo in D. Let CA and CB be sets of duos. We say that the pair (CA,CB) is...
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 ...

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, ...
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)?
The first (hybrid layer peeling) may combine unordered meshes with ordered meshes in an efficient way, and may be well suited for rendering scenes such as volumes with embedded transparent meshes. The second (coherent layer peeling) may efficiently detect and render correctly sorted fragment ...
