Smallest

 
template<class T> Tsmallestintn
T*data
intk )
This function uses the Hoare selection algorithm to return the k-th smallest value in a data set. If on input the order k is 1 the minimum entry is sought, while if k is equal to the size of the array, the maximum is calculated.

Example:

#include <codecogs/statistics/moments/smallest.h>
#include <iostream>
int main()
{
  int x[6] = {1, 5, 2, 3, 8, 7},
  small = Stats::Moments::smallest<int>(6, x, 4);
  std::cout << "The 4th smallest value of the array is: " << small;
  std::cout << std::endl;
  return 0;
}

Output:

The 4th smallest value of the array is: 5
