/*
	Here regular expression we have used is "([a-z])([A-Z])"
	then replacing that matching pattern with "\1 \2". Which means we are searching for a string
	which lower case and upper case letter consecutively. Like aA or bC.
	Then we are using regular expresson back refrencing trick to add a space between these two matching pattern.
	(			#Match and Capture pattern 1
	[a-z]		#must be a lower case alphabet
	)			#End of pattern 1
	(			#Match and Capture pattern 2
	[A-Z]		#must be a upper case alphabet
	)			# End of pattern 2
