# [Solved] 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.

## Question

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.

## Python Solution

```class Solution:
def freqAlphabets(self, s: str) -> str:
k=''
i=0
while i<len(s):
try:
if s[i+2]=='#':
k+=chr(96+int(s[i:i+2]))
i+=2
else:
k+=chr(96+int(s[i]))
except:
k+=chr(96+int(s[i]))
i+=1
return (k)``` ##### Abhishek Sharma
