# Sum of Prefix Scores of Strings solution leetcode

## Sum of Prefix Scores of Strings solution leetcode

You are given an array `words` of size `n` consisting of non-empty strings.

We define the score of a string `word` as the number of strings `words[i]` such that `word` is a prefix of `words[i]`.

• For example, if `words = ["a", "ab", "abc", "cab"]`, then the score of `"ab"` is `2`, since `"ab"` is a prefix of both `"ab"` and `"abc"`.

Return an array `answer` of size `n` where `answer[i]` is the sum of scores of every non-empty prefix of `words[i]`.

Note that a string is considered as a prefix of itself.

Example 1:

```Input: words = ["abc","ab","bc","b"]
Output: [5,4,3,2]
Explanation: The answer for each string is the following:
- "abc" has 3 prefixes: "a", "ab", and "abc".
- There are 2 strings with the prefix "a", 2 strings with the prefix "ab", and 1 string with the prefix "abc".
The total is answer = 2 + 2 + 1 = 5.
- "ab" has 2 prefixes: "a" and "ab".
- There are 2 strings with the prefix "a", and 2 strings with the prefix "ab".
The total is answer = 2 + 2 = 4.
- "bc" has 2 prefixes: "b" and "bc".
- There are 2 strings with the prefix "b", and 1 string with the prefix "bc".
The total is answer = 2 + 1 = 3.
- "b" has 1 prefix: "b".
- There are 2 strings with the prefix "b".
The total is answer = 2.```
