Answer is correct. 2 key point to remember: 1.indexing begins at 0 2.slicing-> [a:b] means start at 'a',go upto BUT NOT INCLUDING 'b' Hence,here employees are indexed 0 thru 199 Removing last 5 makes it 0 to 194 which is represented as [0:195] !!careful the 5 ids are 195,196,197,198,199 -5 -2 -1 3.further ,used concept of negative indexing 4.and [0:c] is same as [:c]
