Hi @kashishsoni,
I have corrected one major bug that was you were checking for uppercase index also which made your array go out of bound . So here is corrected code but your code still does not work for cases such as aaabbbaaa … for this case your code will give output a6b3 but the correct output should be a3b3a3.
here is the link of your code
