Perl script to delete the adjacent repeats !
By Rahul Nayak 1782 days ago
/usr/bin/perl
#Mostly the interview question for bioinfomatician !
#Write a code to delete the adjacent repeated character ....
$string='ATTTTTTGGC'; # This should be converted to ATGC
$string =~ s/(\w)\1/$1/g;
print $string;
#For more helps ... check out this
#This bit of code will do the job:
$string =~ s/(.)\1/$1/g
#Alternatively, if you want to ignore case when comparing, you could use:
$string =~ s/(.)\1/$1/gi
#And finally, if you wanted to trim any number of duplicates down to a single letter, this would work:
$string =~ s/(.)\1+/$1/gi
