(This question has been seen in the interviews of the following companies: Google)
Given 2 strings pin and guess. Write a function to provide a hint that indicates how digits in guess match the pin. Use:
* - to indicate a number in the correct possition.
o - to indicate that a number is present in the pin code but in a different possition.
_ - to indicate that there's no such number in the pin code.
Example 1:
Input: pin = "1432", guess = "1246"
Output: "*oo_"
Explanation:
1 is in the correct position so `*`
2 and 4 are present in the pin code but in different positions thus `oo`
There's no 6 in the pin code thus `_`
Example 2:
Input: pin = "1234", guess = "1234"
Output: "****"
Example 3:
Input: pin = "1234", guess = "5678"
Output: "____"
Example 4:
Input: pin = "1224", guess = "5242"
Output: "_*oo"
Example 5:
Input: pin = "1234", guess = "1224"
Output: "**_*"
Example 6:
Input: pin = "2124", guess = "1224"
Output: "oo**"
Constraints:
pin.length == input.length
The input strings contain only digits 0-9.
