Consider the following code segment. int[][] arr = {{3, 2, 1}, {4, 3, 5}};
for (int row = 0; row < arr. length; row++)
{
for (int col = 0; col < arr[row].length; col++)
{
if (col > 0)
{
if (arr[row][col] >= arr[row][col - 1])
{
System. out. println("Condition one");
}
}
if (arr[row][col] % 2 == 0)
{
System. out. println("Condition two");
}
}
}
As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
A. "Condition one" is printed twice, and "Condition two" is printed twice.
B. "Condition one" is printed twice, and "Condition two" is printed once.
C. "Condition one" is printed once, and "Condition two" is printed twice.
D. "Condition one" is printed once, and "Condition two" is printed once.
E. "Condition one" is never printed, and "Condition two" is printed once.
2. Consider the following code segment.
int[][] arr = {{1, 3, 4}, {4, 5, 3}};
int max = arr[0][0];
for (int row = 0; row < arr. length; row++){
for (int col = 0; col < arr[row].length; col++)
{
int temp = arr[row][col];
if (temp % 2 == 0)
{
arr[row][col] = temp + 1; // line 11
}
if (temp > max)
{
max = temp;
}
}
}
System. out. println(max);
How many times will the statement in line 11 be executed as a result of executing the code segment?
A. 2
B. 3
C. 4
D. 5
E. 6
3. Consider the following method, sumRows, which is intended to traverse all the rows in the two-dimensional (2D) integer array num and print the sum of all the elements in each row.
public static void sumRows(int[][] num)
{
for (int[] r : num)
{
int sum = 0;
for (int j = 0; j < num. length; j++)
{
sum += r[j];
}
System. out. print(sum + " ");
}
}
For example, if num contains {{3, 5}, {6, 8}}, then sumRows(num) should print "8 14 ".
The method does not always work as intended. For which of the following two-dimensional array input values does sumRows NOT work as intended?
A. {{0, 1}, {2, 3}}
B. {{10, -18}, {48, 17}}
C. {{-5, 2, 0}, {4, 11, 0}}
D. {{4, 1, 7}, {-10, -11, -12}}
E. {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}
