+## Resumo
+
+Um juiz online representa uma plataforma essencial em competições de programação, desempenhando o papel crucial de avaliar e classificar as soluções submetidas pelos participantes. Além de ser uma ferramenta valiosa para competições, também serve como um ambiente propício para a exploração e aprendizado de novas linguagens de programação. Nessa plataforma, os participantes enfrentam desafios por meio de questões específicas, e ao submeterem seus códigos, essas submissões são sujeitas a limites rigorosos de tempo e memória, adicionando uma dimensão adicional de desafio e eficiência à avaliação.
+
+
+## Motivação
+
+Nossa motivação é desenvolver um juiz online que adira estritamente aos princípios do Software Livre.

 ## Resumo
 
-Um juiz online representa uma plataforma essencial em competições de programação, desempenhando o papel crucial de avaliar e classificar as soluções submetidas pelos participantes. Além de ser uma ferramenta valiosa para competições, também serve como um ambiente propício para a exploração e aprendizado de novas linguagens de programação. Nessa plataforma, os participantes enfrentam desafios por meio de questões específicas, e ao submeterem seus códigos, essas submissões são sujeitas a limites rigorosos de tempo e memória, adicionando uma dimensão adicional de desafio e eficiência à avaliação.
