Let me clarify what I want to do:
We all know Scrabble game.
there's a file with Dictionary containing word in each line, the idea is
to input some letters for example mentioned earlier: att, the script
supposed to find all words in which letters: 'a','t','t' occur and print
these words. It supposed not to print word: 'auto' because there's only
one 't' but words such as: 'toast', 'toasty', 'tolerant' are meeting the
criteria becase we have in these words one 'a' and two 't' as user has
input.
I've checked collections counter but seems to complicated for me at this
stage yet and I'm struggling with applying it.
