Common LINQ Operations II

While basic filtering and sorting allow us to extract specific data, real-world applications often require deeper analysis. We frequently need to categorize items, compute statistical summaries, or compare entire datasets against one another. Advanced LINQ extension methods provide a concise, declarative syntax to perform these complex operations without writing manual loops.

Grouping data

Organizing data into categories is a frequent requirement in software development. The GroupBy() method allows us to group elements of a sequence according to a specified key selector function.

We group a list of words by their character count.
