Code review "LINQ and string.Split do it yourself practice"

Sept. 28, 2017

Introduction

It is time to review the algorithm again. I posted the question more than 5 month ago, the link is here.

Algorithm Practice

I had a mock interview and the peer chose to use C++ language. I did some research how to translate those four lines of C# code to C++ language.

	var words =
	Regex.Split(sentence, "[ ,?!.]")
	.Select(x => x.Trim())
	.Where(x => !string.IsNullOrEmpty(x))
	.GroupBy(x => x, StringComparer.OrdinalIgnoreCase)
	.OrderByDescending(g => g.Count());
	var summary = $"{{{string.Join(", ", words.Select(g => $"{g.Key}: {g.Count()}"))}}}";

I just could not believe that one day I can write a product using C# advanced feature like LINQ, write regular expression and groupby clause and where clause. I am so excited to set a small goal for my next project.
