Given a string of arbitrary length with any ascii characters. Write a function to determine whether the string contains the whole word “English”.
The order of characters is important — a string “abcEnglishdef” is correct but “abcnEglishsef” is not correct.
Upper or lower case letter does not matter — “eNglisH” is also correct.
Return value as boolean values, true for the string to contains “English”, false for it does not.
