Input is String s= aaabbbccc;
Output is a3b3c3
Test case 2:
Input is String s=aaaabbccc;
Output is a4b2c3
Can u suggest me a code
Or give clues to write code for that

Answer 1

An outline would be-
1. Iterate through the string. 2. When a new letter is found, add the letter to the output string and then add the count of the letter in the string to the output string.

Answer 2

No i tried but i didnt getting logic for count
can u please tell me code

Answer 3

Can you show your attempt pls?
You are already asked similar question..
So can code with information from that.
Give a try,
You can convert to char array or use charAt() method...
Read string in a loop, if i'th char ==i+1 char increase count, continue
Else print i'th char and count, reset count=0,
then continue with next charecters...
If you struck between, then share code,...
