Constraints
All the characters of denote integers between and .
Sample Input
1222311
Sample Output
(1, 1) (3, 2) (1, 3) (2, 1)
Explanation
First, the character occurs only once. It is replaced by . Then the character occurs three times, and it is replaced by and so on.
Also, note the single space within each compression and between the compressions.
