Re: 11730 - Number Transformation

Thanks Asif. I was wrong in my interpretation: from 4 to 12 I was doing: 4 -> 6 -> 8 -> 10 -> 12 = 4 operations. And the correct is 4 -> 6 -> 9 ->12 = 3 operations because after the number are transformed to 6 I can use the prime factor 3 to add. To solve, I used 2 approach: 1) recursive backtrackin...

Re: 11716 - Digital Fortress

Also, You must use (for example):
char text[10001];
to read the line and a output that can store 100x100 chars data
example: char output[101][101];

Dears, only for couriously, there are here some performances tests that I can relate for this problem: Método Execution time bubleSort TLE (> 5 seconds) Qsort Stl with cin / cout 1.072 Quicksort with scanf / printf 0.786 secs (maybe not so good qsort!?)

Re: 10986 - Sending email

Dears. Forget dijkstra and heap, make heap, etc. I have implemented with some variances: 1 - Dijkstra with dinamic list (TLE) (using only #include <cstdio>) 2 - Dijkstra with STL make_heap (TLE) 3 - Dijkstra with heap (like recomended here using only #include <cstdio>) Accepted: tempo: 0.580 (2 days...

Re: 11500 - Vampires - tips

Hi Naffi and Mostafa. You can use to D !=1 also. You must calcule n1 and n2: n1 = EV1/D (rounded to up) page 1 from article n2 = EV2/D (rounded to up) for at = 3 use the formula prob = n1 -------- n1 + n2 else prob = (1- (q/p)^n1 ) ---------------- (1-(q/ *** where (q/p) = (6-at)/at the second prob ...

11500 - Vampires

Hello!

I Found the key to solve:
In http://en.wikipedia.org/wiki/Gambler%27s_ruin You can find the Both Formulas
The first one is to solve when AT = 3 (P2 = n1/(n1+n2))
The second one is to solve when AT != 3 (P1 = 1- (q/p)^n1... where q = (6-AT)/AT ...

Re: 11492 - Babel

Dear Anindya. I don´t know if you correct your code, anyway the error is because a small test is missing (bold) if(u==st) { x=adj ; v=x.dest; lv=x.cost[0]-'a'; if (x.cost.size() < dis[v][lv]) dis[v][lv]=x.cost.size(); x.tot=dis[v][lv]; q.push(x); } if you use the same map with bellman-ford you can o...
