1309. Decrypt String from Alphabet to Integer Mapping
Description
You are given a string s
formed by digits and '#'
. We want to map s
to English lowercase characters as follows:
- Characters (
'a'
to'i'
) are represented by ('1'
to'9'
) respectively. - Characters (
'j'
to'z'
) are represented by ('10#'
to'26#'
) respectively.
Return the string formed after mapping.
The test cases are generated so that a unique mapping will always exist.
Example 1:
Input: s = "10#11#12" Output: "jkab" Explanation: "j" -> "10#" , "k" -> "11#" , "a" -> "1" , "b" -> "2".
Example 2:
Input: s = "1326#" Output: "acz"
Constraints:
1 <= s.length <= 1000
s
consists of digits and the'#'
letter.s
will be a valid string such that mapping is always possible.
