Given a string word, compress it using the following algorithm:
Return the string comp.
Examples
Example 1
Input: word = "abcde"
Output: "1a1b1c1d1e"
Explanation:
Initially, 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
Input: word = "aaaaaaaaaaaaaabb"
Output: "9a5a2b"
Explanation:
Initially, comp = "" . Apply the operation 3 times, choosing "aaaaaaaaa" , "aaaaa" , and "bb" as the prefix in each operation.
Constraints
1 <= word.length <= 2 * 105
word consists only of lowercase English letters.
