Let's teach the Robots to distinguish words and numbers.

You are given a string with words and numbers separated by whitespaces (one space). The words contains only letters. You should check if the string contains three words in succession . For example, the string "start 5 one two three 7 end" contains three words in succession.

Input: A string with words.

Output: The answer as a boolean.

Example:

checkio("Hello World hello") == True
checkio("He is 123 man") == False
checkio("1 2 3 4") == False
checkio("bla bla bla bla") == True
checkio("Hi") == False

How it is used: This teaches you how to work with strings and introduces some useful functions.

Precondition: The input contains words and/or numbers. There are no mixed words (letters and digits combined).
