Chapter 7, Problem 10E
Write a static method remove {int v, int [] in} that will return a new array of the integers in the given array, but with the value v removed. For example, if v is 3 and n contains 0, 1, 3, 2, 3, 0, 3, and 1, the method will return an array containing 0, 1, 2, 0, and 1.

Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.
Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different.
For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).
3.
write a method called insert that inserts an element into an integer array. It should take 3
parameters: an int array, the number to be inserted and the index it should be inserted at. It
should return a new array that has the element inserted at the index (the new array should have
a length 1 longer than the original array).
Sample code
int[] a = {1,2,3,4,5};
int[] inserted = insert (a,9,0);
printArray (inserted);
int [] a = {1,2,3,4,5};
int[] inserted = insert (a,9,3);
printArray(inserted);
int [] a = {1,2,3,4,5};
int[] inserted = insert(a,9,5);
| printArray(inserted);

- The rotateLeft method takes an array of integers, and an integer number of places, and returns a new copy of the array that contains a "rotated" version of the input array. Rotation means that elements have been shifted leftwards by that number of places, moving elements off one end of the array and onto the other end. For example, [11, 12, 13, 14, 15] rotated left by 2 places results in [13, 14, 15, 11, 12].arrow_forward. - Write a method called checkArrays that accepts as parameters two arrays of integer (A and B of the same size) and returns another array of integers (C) initialized as follows: C[i] = 1 if B[i] divides A[i], otherwise C[i]=0.
