Select / Print odd-even elements of an array

Hello experts,

I wish to print the contents of odd-even numbered indices of an array.

The problem statement is as follows :

1. The first line contains an integer, (the number of test cases).
2. Each line of the subsequent lines containing a string.

Example:

Code:
2
Haider
Bash


Explanation:

Code:
A[0]=H
A[1]=a
A[2]=i
A[3]=d
A[4]=e
A[5]=r


X[0]=B
X[1]=a
X[2]=s
X[3]=h


The expected output :

Hie adr :: The first elements are the even indexed elements are displayed followed by a space, followed by the odd indexed elements of array 1.
Bs ah :: The first elements are the even indexed elements are displayed followed by a space, followed by the odd indexed elements of array 2.

Code written so far :

Code:
read n
read -a arr1
read -a arr2

Could you please help.

Thanks,
Haider

Mod Comment Thanks for using code tags, but usually you don't have to put code tags inside code tags. I removed some to make it a bit more readable.

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
