List and explain the worst-case and average-case running times
for each Vector method below:
(a) insert(iterator here, Object item)
(b) insertAtHead
(c) insertAtTail (aka push back)
(d) get(iterator here)
(e) get(index i)
(f) remove(iterator here)
(g) remove(index i)
(h) splice(iterator place here, iterator from here, iterator to
here)
(Be sure you understand when (and why) push back runs in constant
average time.)
Homework Answers
(a) insert(iterator here, Object item)
Worst case running time: O(1)
Average case running time: O(1)
(b) insertAtHead
Worst case running time: O(1)
Average case running time: O(1)
(c) insertAtTail (aka push back)
Worst case running time: O(n)
Average case running time: O(n)
(d) get(iterator here)
Worst case running time: O(1)
Average case running time: O(1)
(e) get(index i)
Worst case running time: O(n)
Average case running time: O(n)

Lab 6 (ALL CODING IN JAVA)
Problem: A text file contains a paragraph. You are to read the
contents of the file, store the UNIQUEwords and count the
occurrences of each unique word. When the file is completely read,
write the words and the number of occurrences to a text file. The
output should be the words in ALPHABETICAL order along with the
number of times they occur and the number of syllables. Then write
the following statistics to...
