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 . Suppose a character '' occurs consecutively times in the string. Replace these consecutive occurrences of the character '' with in the string. For a better understanding of the problem, check the explanation. Input Format A single line of input consisting of the string . Output Format A single line of output consisting of the modified string. 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
