Sir you are awesome .I can understand the concepts clearly.

When you talk about substring and count the index you do not count the space as a character. I am confused because when we counted the string length it was 15 but now you are saying that A (in Academy) is at index 8 and d (in Academy) is at index 11 but shouldn't they be respectively at index 9 and 12?
Thanks for your videos . I absolute love them.

Sir you did great in this video. It was so helpful in my examination. But you could have said that space is also added while counting the

He forgot to mention that those methods don't change the value of the string, they return another string instead .
