Dear Masters,

my $str_type1 = "ccaatTTTGACACACACAGAAgggca"; # no dash
my $str_type2 = "--aatTTTGACACACACAGAAgggca"; # with dash 

# note: number of dash(es) can be >= 0

How can we have the universal function to identify the starting and ending position of the uppercase substring from 2 kinds of string above.
Index of the superstring is counted when 'atcgn' is found first. So for example

• Type 1, index start at base "c", thus the Uppercase has start_pos = 6 and end_pos = 21
• Type 2, index start at base "a", thus the Uppercase has start_pos = 4 and end_pos = 19
