## Algorithm

Problem Name: Python - Compress the String!

In this HackerRank Functions in PYTHON problem solution,

In this task, we would like for you to appreciate the usefulness of the groupby() function of itertools . To read more about this function, Check this out .

You are given a string S Suppose a character 'c' occurs consecutively X times in the string. Replace these consecutive occurrences of the character 'c' with (X,c) in the string.

For a better understanding of the problem, check the explanation.

Input Format

A single line of input consisting of the string S.

Output Format

A single line of output consisting of the modified string.

Constraints

All the characters of S denote integers between 0 and 9.

1 <= |S| <= 10**4

Sample Input

1222311


Sample Output

(1, 1) (3, 2) (1, 3) (2, 1)


Explanation

First, the character 1 occurs only once. It is replaced by (1,1) . Then the character 2 occurs three times, and it is replaced by (3,2) and so on.

Also, note the single space within each compression and between the compressions.
