Given Files:

selection.h

#ifndef SELECTION_H

#define SELECTION_H

 

#include <cstddef>

 

int select(size_t k, const int* list, size_t N);

 

#endif // SELECTION_H

 

selection.cpp

#include <stdexcept>

#include "selection.h"

 

int select(size_t k, const int* list, size_t N) {

// TODO(student): solve the selection problem

Task 1
Write a program to determine (select) the k-th largest value in a list of Nvalues.
Requirements
Files
selection.cpp
selection.h
selection_tests.cpp
Function
int select(size_t k, const int* list, size_t N);
Input
k :- the rank of the desired value, o <k <=N
list := the collection of values from which to select
N := the number of values in the list, N > e
Output
The value which is the k-th largest in the list.
Exceptions
Throws std::invalid_argument if the arguments are
invalid, e.g. k is out of bounds.
Approv ed Includes cstddef, iostream, stdexcept, selection.h
Tests
You must submit a test suite that, when run, covers
at least 90% of your code.
Example
Consider the list A = (8, 6, 7, 5, 3, 0, 91.
select (2, A, 7)
select(4, A, 7) returns
