Question
What is the runtime of the following code segments? Prove that your answer is correct.
1.
void foo(int* array, int size)
{
int sum = 0;
int product = 1;
for (int i=0; i < size; i++)
{
sum += arrray[i];
}
for (int i =0; i < size; i++)
{
product *= array[i];
}
cout << sum << " ," << product;
}
2.
void printPairs ( int * array, int size) {
for (int i=0; i<size; i++)
for (int j=0; j < size; j++)
cout << array[i] << " + " << array[j];
}
3.
void reverse(int * array, int size) {
for (int i=0; i<size/2; i++)
{
int other = size - i-1;
int temp = array[i];
array[i] = array [other];
array[other] = temp;
}
}
