# ch-2.pl Perl Weekly Challenge 250 Task 2 Alphanumeric String Value
#=============================================================================
# You are given an array of alphanumeric strings.
# Write a script to return the maximum value of alphanumeric string in
# the given array. The value of alphanumeric string can be defined as
# a) The numeric representation of the string in base 10 if it is made
# up of digits only. b) otherwise the length of the string
# Example 1 Input: @alphanumstr = ("perl", "2", "000", "python", "r4ku")
# Output: 6
# Example 2 Input: @alphanumstr = ("001", "1", "000", "0001")
# Output: 1
