# Decode Ways LeetCode Solution

## Decode Ways LeetCode Solution

• A message containing letters from A-Z can be encoded into numbers using the following mapping:
• ```'A' -> "1"
'B' -> "2"
...
'Z' -> "26"```

## Decode ways LeetCode Solution:

To decode an encoded message, all the digits must be grouped then mapped back into letters using the reverse of the mapping above (there may be multiple ways). For example, `"11106"` can be mapped into:

• `"AAJF"` with the grouping `(1 1 10 6)`
• `"KJF"` with the grouping `(11 10 6)`

Note that the grouping `(1 11 06)` is invalid because `"06"` cannot be mapped into `'F'` since `"6"` is different from `"06"`.

Given a string `s` containing only digits, return the number of ways to decode it.

The test cases are generated so that the answer fits in a 32-bit integer.
