Exercise 07a. Check the idempotence of the 'closing-opening' alternated filters for a particular case, using the programs implemented in previous exercises:
After the following calls, where 'i' denotes the size (an integer number):
exercise_06a_closing_opening i exercise_06a_input_01.pgm exercise_06a_output_01.pgm ~ exercise_06a_closing_opening i exercise_06a_output_01.pgm exercise_06a_output_02.pgm ~ exercise_02b_compare exercise_06a_output_01.pgm exercise_06a_output_02.pgm exercise_02b_output_01.pgm
The 'exercise_02b_output_01.pgm' file should contain: '~'
