Cada colônia começa com uma bactéria, divide-se gerando D bactérias por noite e cresce por C noites. editorial: | **Briefing para o Professor:** O problema clássico do crescimento exponencial. O grande truque de Matemática Discreta neste desafio é que a fórmula do crescimento de bactérias é `D^C`. Como os valores de `D` e `C` podem ser até os milhares, `D^C` geraria números colossais (Time Limit Exceeded e estouros de memória em linguagens com tipagem forte como C++ ou Java que só chegam até 64 bits). A grande jogada é aplicar os logaritmos! A maximização de `D^C` é igual à maximização de `log(D^C)`. Pela propriedade do Tombo dos Logaritmos, `log(D^C) = C * log(D)`. Este valor pode ser calculado instantaneamente usando double! **Estratégia de Resolução:** Leia `N`. Inicialize um rastreador do melhor valor: `max_val = -1` e `best_idx = -1`. Em um loop, para cada iteração $i$ (de 0 até N-1): - Leia `D` e `C`. - Faça `val = C * log(D)`. - Se `val > max_val`, atualize `max_val` e guarde `best_idx = i`. Imprima `best_idx`. successmsg: 'Parabéns! Você descobriu a propriedade do tombo dos logaritmos para evitar números astronômicos.' timeComplexity: O(N) skills: - basic-math - floating-point statements: - id: a-feira-de-bacteria testScenarioLevel: A thematicSkills: - skill: history points: 1 testScenarios: - id: a-performance name: Centenas de Colônias description: "Milhares de colônias sendo analisadas com números na faixa de grandeza dos 10000." helpTip: "Estourou memória ou deu Time Limit?
