body: <p>I've been trying to figure out, the best way to tackle this problem.</p>
  
  <p>The problem Im stuck on is where I need to take the user input(word) and put it in the array and try to confirm/validate if all the letters they've use are in the char array(generates 10 random letters)(letterpool) then check again if the word they've use are valid from the dictionary. </p>
