in reply to Find out missing floating value in an array

Hi

I think your array contains the element from 1 to 20 with the preceeding of "1."

You can find the missing element by generating the dummy array having all the elements with the increment value and the last element value, to compare with the original input array. Like

use strict; use List::Compare::Functional qw(:originals :aliases); my @argen = (1..20); map{s/^/1./} @argen; #To create the dummy array having all the elem +ents with the increment value and the last element value my @arin=("1.1","1.2","1.3","1.4","1.5","1.7","1.10"); #Consider the e +lement in string, if not it will treat "1.10" as "1.1" my @ardif = get_unique( [ \@argen, \@arin ] ); #it gives the elemen +ts present in the first but not present in second if(@ardif){ $"=", "; print "The missing elements are: @ardif"; }
