Assignment: World Bank Real GDP & Growth (CSV version)

⚠️ Overall Assessment

Result: ⚠️ Partially correct

The code runs and correctly loads the dataset, but execution stops with the following runtime error: Index exceeds the number of array elements. Index must not exceed 1. Error in week3_homework_chiaratombolini (line 46) country_name = split_name{4};

This is the same issue encountered by several students: the script tries to extract the country name from the filename instead of the dataset itself. Everything else appears well structured, so this is a minor but blocking error.
