Question

iven the following sorted vector of integers:

 
 
 
 
 
// index 0 1 2 3 4 5 6 7 8 9 10 11 12 13vector<int> v {-23, -5, 9, 14, 15, 18, 23, 24, 25, 27, 34, 62, 85, 87};
 

What indexes are examined in a search for each value, and what value is returned?

 
sequential search for 27
  1. A examines 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13; returns 9
  2. B examines 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; returns 27
  3. C examines 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; returns 9
  4. D examines 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13; returns 27
  5. E examines 13, 12, 11, 10, 9; returns 9
(order shuffled)
binary search for 27
  1. A examines 6, 8, 10; returns 9
  2. B examines 6, 10, 8, 9; returns 9
  3. C examines 6, 9; returns 9
  4. D examines 6, 3, 1; returns -1
  5. E examines 7, 10, 9; returns 9
(order shuffled)
