'Uniq' Command #3.sh

#Given a text file, count the number of times each line repeats itself (only consider consecutive repetions). Display the count and the line, separated by a space. There shouldn't be leading or trailing spaces. Please note that the uniq -c command by itself will generate the output in a different format.

#This time, compare consecutive lines in a case insensitive manner. So, if a line X is followed by case variants, the output should count all of them as the same (but display only the form X in the second column).

#So, as you might observe in the case below: aa, AA and Aa are all counted as instances of 'aa'.

#-i parameter allows us to ignore case sensitivity.
