/* Write a C# program to display characters and frequency of characters from a given string.
• The program should do case-insensitive comparisons and ignore white spaces.For ex: if the string is “Arden Hills”, ignore the white space and treat it as one string “ArdenHills”
• Only alphanumeric characters are allowed.
• Bonus points for using LINQ and strongly typed variables.
It is OK to use Google for syntax etc. (no generative UI and searching exact code samples)*/
