Wordle

Create a program, which, given a 5 character string as a target word, and a 5 character string as a guess, return a 5 character string where:

‘2’ = this letter is in this position
‘1’ = this letter is in the target word but not this position
‘0’ = this letter is either not in the target word, or is not in the target word as many times as it is in the guess

Examples

No matching characters

Target = “ropes”
Guess  = “child”
Result = “00000”

Characters match in correct positions

Target = “alert”
Guess  = “alarm”
Result = “22020”

Character in wrong position

Target = “stair”
Guess  = “chore”
Result = “00010”

Mix of match and wrong position

Target = “hairy”
Guess  = “charm”
Result = “01120”

Multiple of the same character

Target = “reads”
Guess  = “elect”
Result = “10000”

In this example, only the first instance of e in the guess is given a 1 because there is only one e in the answer, and neither matched exactly.

Target = “doubt”
Guess  = “trait”
Result = “00002”

In this example, the second instance of t in the guess is given a 2 because there is only one t in the answer and the second has matched exactly.
