⭐️ Update the video
At 2:13 I say index number usually starts from 0. But right reason to add + 1 is that the difference R - L represents the number of positions between the two indices, not the number of elements including both ends. To correctly count all characters from L to R, including both endpoints, we need to add 1. This ensures the length includes both the starting and ending characters.
