Given a string word, compress it using the following algorithm:
comp. While word is not empty, use the following operation:\n\n\tword made of a single character c repeating at most 9 times.c to comp.Return the string comp.
\n
Example 1:
\n\nInput: word = "abcde"
\n\nOutput: "1a1b1c1d1e"
\n\nExplanation:
\n\nInitially, comp = "". Apply the operation 5 times, choosing "a", "b", "c", "d", and "e" as the prefix in each operation.
For each prefix, append "1" followed by the character to comp.
Example 2:
\n\nInput: word = "aaaaaaaaaaaaaabb"
\n\nOutput: "9a5a2b"
\n\nExplanation:
\n\nInitially, comp = "". Apply the operation 3 times, choosing "aaaaaaaaa", "aaaaa", and "bb" as the prefix in each operation.
"aaaaaaaaa", append "9" followed by "a" to comp."aaaaa", append "5" followed by "a" to comp."bb", append "2" followed by "b" to comp.\n
Constraints:
\n\n1 <= word.length <= 2 * 105word consists only of lowercase English letters.Compiled with clang 17 using the latest C++ 20 standard, and libstdc++ provided by GCC 11.
