14. Consider the following function.
#include <algorithm>
double mystery (double data[], int length)
std::sort (data, data+length);
bool length_is_odd = length % 2;
if (length_is odd)
length / 2;
return data [middle_idx] ;
int middle_idx =
else
data[(length / 2) - 1];
data[length / 2];
double mid1 =
double mid2 =
return (mid1 + mid2) / 2.0;
(a) Suppose data =
{1, 2, -6 , 5} and length
= 4.
• What would data look like after std::sort executes?
• What is the value of length½2?
• What is the value of length/2?
• Is the if or else branch executed?
• What value is returned from the function?
