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

\n\n

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

\n\n\n\n

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

\n\n

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

\n\n

Example 1:

\n\n
\nInput: words = ["abc","ab","bc","b"]\nOutput: [5,4,3,2]\nExplanation: The answer for each string is the following:\n- "abc" has 3 prefixes: "a", "ab", and "abc".\n- There are 2 strings with the prefix "a", 2 strings with the prefix "ab", and 1 string with the prefix "abc".\nThe total is answer[0] = 2 + 2 + 1 = 5.\n- "ab" has 2 prefixes: "a" and "ab".\n- There are 2 strings with the prefix "a", and 2 strings with the prefix "ab".\nThe total is answer[1] = 2 + 2 = 4.\n- "bc" has 2 prefixes: "b" and "bc".\n- There are 2 strings with the prefix "b", and 1 string with the prefix "bc".\nThe total is answer[2] = 2 + 1 = 3.\n- "b" has 1 prefix: "b".\n- There are 2 strings with the prefix "b".\nThe total is answer[3] = 2.\n
\n\n

Example 2:

\n\n
\nInput: words = ["abcd"]\nOutput: [4]\nExplanation:\n"abcd" has 4 prefixes: "a", "ab", "abc", and "abcd".\nEach prefix has a score of one, so the total is answer[0] = 1 + 1 + 1 + 1 = 4.\n
