Say there is a specific string : bacdefaxyza.
Now the character a is repeated 3 times. I now want to be able to delete or replace with "" only the a in the middle but not all. Is there a way to do so? i.e. : I need to be able to delete that a from any place I wish ( index of that character is known ). Is it possible?
I tried using the replace() function but it deletes only the first occurrence, or more, but not at a particular index/place that I need.
