Big data
- Big data is a combination of structured, semi structured and unstructured data collected by organizations.
- These data can be mined for information and can be used in machine learning projects.
- Big data is larger and more complex data sets obtained from new data sources.

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.

For coding simplicity, follow each output integer by a space, including the last one. Then, output a newline.
