Choose the correct option.
What is the method dimen() performing?
- (i)Finding the product of the boundary elements
- (ii)Finding the sum of the non-boundary elements
- (iii)Finding the sum of the boundary elements
- (iv)Finding the sum of the matrix elements
Show the code
void dimen(int n[][])
{
int p = 0;
for (int i = 0; i < n.length; i++)
for(int j = 0; j < n[0].length; j++)
{
if(i == 0 || i == n.length - 1 || j == 0 || j == n[0].length - 1)
p = p + n[i][j];
}
System.out.print(p);
}Answer
Answer
AICorrect option: (iii)
Answer: (iii) Finding the sum of the boundary elements
The condition selects the first/last row and first/last column, and their values are added to p.
