Of the source code for merge sort in 10th lecture, there are several sort of "i = i+1" lines. I tried them with "i += i", which got the programme into inf.loop. Can anyone explain why does it happen? I thought "i = i+1" and "i += i" are quietly same thing, was I wrong?

That convention is not supported in every programming language.

whoops, my bad.
'i += i' is not identical to 'i = i + 1'
'i += 1' IS identical to 'i = i + 1'

A basic mistake have I made.
