Write a Java program that randomly generates an
array of 500,000 integers between 0 and 499,999, and then prompts
the user for a search key value. Estimate the execution time of
invoking the linearSearch method in Listing A below. Sort the array
and estimate the execution time of invoking the binarySearch method
in Listing B below. You can use the following code template to
obtain the execution time:
long startTime = System.currentTimeMillis();
perform the task;
long endTime = System.currentTimeMillis();
long...

For each pseudo-code function below (after the next ==== line), write a useful loop invariant capturing correctness for the
main loop in each of the following programs and briefly argue initialization, preservation, and termination.
EXAMPLE PROBLEM:
//Function to return the max of an array A
Maximum(array of integers A)
Local integer
integer m
m=0
for i = 1 to n
if A[i] > m
then m = A[i]
end function Maximum
EXAMPLE SOLUTION:
The loop invariant is m = max(0,...

The one missing piece was inserting into a binary search tree;
we'll take care of that today and write the insert
function, as well as a height function. Both
functions will be implemented in the "bst.h" header file, and
tested using a provided main program in "main.cpp".
Step one is to implement the insert function
--- go ahead and modify "bst.h", adding the necessary code to (1)
allocate a new node, and (b) link it into the tree. Once you...

[15 pts.] Consider a version of a binary
search tree (BST) for sorted maps with integer keys that
stores additional information as data members of each node
w of the tree to account for the smallest and largest
integer keys in the subtree rooted at w. Suppose that we
can access this information using w.min, for the smallest
integer key, and w.max, for the largest. Algorithm 4
provides the pseudocode for the constructor of a node in a binary
tree...
