How to solve Minimize Distinct ?
Every unique number less than L will stay so that count is same. For L to R each gets +1 and after R each gets -1 so notice how R we can get from R-1 or R+1 . R+1 can get from R+2 or R .
Now go ahead you will see answer can only be total distinct count, tdc-1 or tdc-2.
