Question
Implement a method named insert. This method should take an array of ints, the
index at which a new value should be inserted, and the new value that should be inserted. The
function should return a new array populated with the contents of the original array with the
given value inserted at the given index. The following sections provide a detailed description of
this function:
Method signature:
static int[] insert (int[] array, int index, int value)
Parameters:
array
The original array of ints.
index
The location where the value will be inserted.
value
The value to be inserted.
Return value:
A new array of ints containing the contents of the original array plus the new value
inserted at the given index.
Pseudocode:
// Create new array one larger than original array
Let newArray = a newArray with array.length + 1 elements
// Copy elements up to insert point from original array to new array
Loop to copy array [0, index) to newArray [0, index)
// Place insert value into new array
Set newArray[index] to value
// Copy elements after insert point from original array to new array
Loop to copy array[index, length) to newArray[index + 1, length + 1)
Return newArray
