You are given a string . Suppose a character ‘a’ occurs consecutively n times in the string. Replace these consecutive occurrences of the character ‘a’ with (n, ‘a’) in the string.
Input Format: A single line of input consisting of the string .
Output Format: A single line of output consisting of the modified string.
(1, 'a') (3, 'b') (1, 'c') (3, 'd') (2,'a')
First, the character ‘a’ occurs only once. It is replaced by (1,’a’). Then the character ‘b’ occurs three times, and it is replaced by (3,’b’) and so on. Also, note the single space after comma and between ‘) (‘.
- += Could join string together
- need use for loop to read every character
- if you do not know how to write python code please write down the logic thoughts.
