Java Exit TicketDirections: Answer the following questions in the time allotted.Assume that myNums is instantiated and populated as follows:int [] myNums = new int [2] [3] ;for( int row = 0; row < myNums.length; row++ )for( int col = 0; col < myNums [0].length; col++ )myNums [row] [col] = 2 * row + 1;{Determine the value of myNums(1] [2] and show how you arrive at your answer:2. myNums [1] represents a(n).of myNums.3. myNums.length represents the number of.in myNums.4. myNums[0].length represents the number of.in myNums.5. Write Java code to print out the column at index 1 of myNums.Bonus! Write code to find a print the average of all the numbers in the last column of myNums.

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }
X42: frontPiece Given an int array of any length, return a new array of its first 2 elements. If the array is smaller than length 2, use whatever elements are present. Examples: frontPiece ({1, 2, 3}) -> {1, 2} frontPiece ({1, 2}) -> {1, 2} Your Answer: Feedback Your feedback will appear here when you check 1 public int[] frontPiece(int[] nums) 2 { your answer. 3 4 }
Shift Left k Cells Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
