Need to create a hash table from csv file. Starting from sample code's, I'm getting error. I don't know do i need to use hash_ref to recognize(add/modify) hash table. Hash table should contain contents of Column1 and Column5 from CSV file. Hash $keys need to be Column5 and corresponding $values to be Column1. Later, I'll refer/replace Column1 to edit other task. Please help me how to solve these task! Thanks
