Analyze the following code. public class Test { public static void main (String ] args) { int [] [] matrix = {{3, 2}, (7, 9, 5},{4, 8, 2, 6}}; System.out.-println ("matrix[1] [3] is " + matrix[1] [3]); } The program has a compile erTor because the size of the array wasn't specified. O The program runs fine and displays matrix[1][3] is 5. The program has a runtime error because the index is out of the array bounds. O The program runs fine and displays matrix[1][3] is 0.

ii) In JAVA language input the elements of an integer array A of size 10 and find the count of all hills in the array. A[i] is a Hill if A[i-1]A[i+1]. A[i] >= 0 All elements of the array are unique.

JAVA Language: Transpose Rotate. Question: Modify Transpose.encode() so that it uses a rotation instead of a reversal. That is, a word like “hello” should be encoded as “ohell” with a rotation of one character.

Consider the following C program: static int sum = 0; void fill (int* a, int l1) { for (int i = 0; i < 1; i += 1) { a[i] = i * i; sum = sum + a[i]; } int main (int argc, char** argv) { int length = 5; %3D int* array malloc (length * sizeof (int)); %3D fill(array, length); return sum; } Identify each of data spaces that will be exist during the lifetime of this program when it runs, and for each: (a) Specify when it would be allocated. (b) Specify in which region of the address space it would be placed. (c) Indicate how the space is created.
