# Task 1: Sort Language
# =====================
#
# You are given two array of languages and its popularity.
#
# Write a script to sort the language based on popularity.
# Example 1
#
# Input: @lang = ('perl', 'c', 'python')
#        @popularity = (2, 1, 3)
# Output: ('c', 'perl', 'python')
#
# Example 2
#
# Input: @lang = ('c++', 'haskell', 'java')
#        @popularity = (1, 3, 2)
# Output: ('c++', 'java', 'haskell')

# The solution that jumps right into my face is to fill the data
# into a hash table, using lang as the key and popularity as the
# value. Then sort the keys by their values and put the result into
# the output.
