Another simple calculation is that of finding the largest element in a list.
This is an obvious
operation... in fact, the total
number of comparisons is just n-1.
int max( vector<int> & data )
{
int max = data[0];
for( int i = 1; i < data.size(); i++ )
if( data[i] > max )
max = data[i];
return max;
}
