Hello, @sp5513,

Change the below line,

return remove_duplicates(arr,n-1,i+1);

to

return remove_duplicates(arr,n-1,i);

We don’t need to increment i here as the size of the string is reduced by 1, and we need to check again at the present index.

For example, let string = aaa
now after the first step string becomes => aa
now we need to check at the present index again so that in the next step it is further reduced to “a”
