Consider the following JavaScript program:

var x, y, z;
function sub1() {
var a, y, z;
function sub2() {
var a, b, z;
. . .
}
. . .
}
function sub3() {
var a, x, w;
. . .
}

List all the variables, along with the program units where they are declared, that are visible in the bodies of sub1, sub2, and sub3, assuming static scoping is used.

Write a method in the heapintpriorityqueue class called merge that accepts another heapintpriorityqueue as a parameter and adds all elements from the other queue into the current queue, maintaining proper heap order such that the elements will still come out in ascending order when they are removed. your code should not modify the queue passed in as a parameter. (recall that objects of the same class can access each other's private fields.)

When copying and pasting text, the first step is move your cursor type the text select the copy command select the paste command
