In the case of multiple numbers are correct, for example you answered "1345".
The status of "1" is "1H" because it's correct in both number and position.
"3" and "4" are correct in only number, then the status is "2B".
In the result, "1H2B" is shown as follows.

1345 1H2B

Please repeat to answer all 4 digits are correct in both numbers and positions.
