# Sort
Una programa que deja ejecutar varios algoritmos de ordenamiento.
Una programa que deja ejecutar varios algoritmos de ordenamiento con el próposito de de comprobar la diferencia en rendamiento de los algoritmos.

## Autores
Christopher Cromer

Rodolfo Cuevas

## Compilar
Hay tres blancos disponible para usar con GNU Make:

make sort
Compilar el programa

make test
Comprobar que los algoritmos y programa corren como esperado

make informe
Compilar el informe si pdflatex está disponible en el sistema
