[BOJ 12466] Runs (Large)
View as PDFI have a string S consisting of lower-case alphabetic characters, 'a' - 'z'. Each maximal sequence of contiguous characters that are the same is called a "run". For example, "bookkeeper" has 7 runs. How many different permutations of S have exactly the same number of runs as S?</p>
Two permutations a and b are considered different if there exists some index i at which they have a different character: a[i] ≠ b[i].
입력 형식
The first line of the input gives the number of test cases, T. T lines follow. Each contains a single non-empty string of lower-case alphabetic characters, S, the string of interest.</p>
Limits
- 1 ≤ T ≤ 100.
- S is at least 1 character long.
- S is at most 450000 characters long.
- S has at most 100 runs.
- The input file will not exceed 1 megabyte in size.
For each test case, output one line containing "Case #x: y", where x is the case number (starting from 1) and y is the number of different permutations of S that have exactly the same number of runs as S, modulo 1000003.
