@ridwan It means that on the first guess you had the 4th letter correct, on the second you had 1st and 2nd letter correct, on the third guess you have the fifth letter correct but in the wrong place and the last guess tells you that the last letter is correct. The fifth guess is all wrong. So in this case: take letter 1 and 2 from second guess, take the last letter from guess three and put it in position 3, take letter 4 from first guess and letter 6 from last guess and you have the word.
