Questions
I wаnt tо cоunt the wоrds from one of the Linux dictionаries files, locаted at /usr/share/dict/american-english, that contain two successive vowels, immediately preceded and followed by the same letter. These words must be of a length between 4 and 8 characters. Please note: The file /usr/share/dict/american-english is available on the vmportal.cse.usf.edu Linux virtual machines. If it is not available on your system, like for instance on the USF student cluster, then use a small file that you make yourself with one word per line. Chose the words that you use so that that file is relevant to testing in the context of this question.
