(Find the Minimum Value in a vector) Modify your solution to Exercise 6.37 to find the minimum value in a vector instead of an array.

Question

What will be an ideal response?

```
#include

using namespace std;

const int MAXRANGE = 1000;
int recursiveMinimum( const vector< int > &, int, int );

int main()
{
vector< int > array( 10 );
int smallest;

srand( time( 0 ) );

// initialize elements of array to random numbers
for ( size_t loop = 0; loop < array.size(); loop++ )
array[ loop ] = 1 + rand() % MAXRANGE;

// display array
cout << "Array members are:\n";

for ( size_t k = 0; k < array.size(); k++ )
cout << setw( 5 ) << array[ k ];

// find and display smallest array element
cout << '\n';
smallest = recursiveMinimum( array, 0, array.size() - 1 );
cout << "\nSmallest element is: " << smallest << endl;
} // end main

// function to recursively find minimum array element
int recursiveMinimum( const vector< int > &array, int low, int high )
{
static int smallest = MAXRANGE;

// if first element of array is smallest so far
// set smallest equal to that element
if ( array[ low ] < smallest )
smallest = array[ low ];

// if only one element in array, return smallest
// else recursively call recursiveMinimum with new subarray
return low == high ?
smallest : recursiveMinimum( array, low + 1, high );
} // end function recursiveMinimum
```
Array members are:
117 433 783 387 485 157 10 715 287 774
Smallest element is: 10
