Problem Statement

Problem Statement

We are looking for occurrences of the string "red" in a piece of text. For example, in the text 

    the detective questioned his credibility

we find "red" inside the word "credibility".

Capitalization doesn't matter, so in the text 

    Server ERRED in Redirecting Spam

we find "red" at the end of "ERRED", as well as at the beginning of "Redirecting".

Given a String, count the number of times "red" appears in it with any capitalization.

Constraints

  • text will contain between 1 and 50 characters, inclusive.
  • text will contain only letters ('A'-'Z', 'a'-'z') and spaces (' ').
