Question 9
Evaluate:
Solution
Providing a range like [-5:-10] is effectively the same as [-5:-10:1], where the index count tries to increase from -5 to -10.
However, since going from -5 to -10 is in a decreasing direction, 'mangosteen'[-5:-10] results in an empty string, i.e., ''.
This is different from 'mangosteen'[-5:-10:-1], where you indicate a decrease in index count to 'sogna'.
Hence, 'mangosteen'[-5:-10] + ' juice' \(\Rightarrow\) '' + ' juice' \(\Rightarrow\) ' juice'
