Pedro was disappointed because he didn't speak Python well enough to capture some of the flags on CTFLearn. His plan for revenge was to create one in his native language (Java). The flag is a String of 6 alphanumeric characters. Capture it. https://mega.nz/#!SHp1xCAL!I9-Zy4kwu_JY019MiYZ6CzGey8sJ6UvqE-ML2idmkrs

        make sure you read the assignment carefully, the flag consists of alphanumeric characters only :)
