Algorithm Analysis: Study the following sorting algorithm.
SORT( A[1...n])
bound <- Length(A) -1
for i <- 1 to Length(A)
newbound <- 0
for j <- 0 to bound
if A[j] > A[j + 1]
swap( A[j], A[j + 1] )
newbound = j -1
bound <- newbound
(a) Use the longer approach described in lecture 3 week 1 that we
used in analyzing Insertion-Sort to compute the running time T(n)
of the above SORT algorithm. You may need to define variable such
as ti or tj, similar to the variable tj we used in the lecture.
(b) Determine the worst case running time and the best case running time as a function of functions of n.

Bubble sort is a popular, but inefficient, sorting algorithm. It works by repeatedly swapping adjacent elements that out of order. BUBBLESORT(A) 1. for i = 1 to A.length – 1 2. for j = i + 1 to A.length 3. if A[j] < A[i] 4. exchange A[j] with A[i] a) A loop invariant for the outer for loop in lines 1 – 4 is: At iteration i, the sub-array A[1..i] is sorted and any element in A[i+1..A.size] is greater or...

Insertion sort on small arrays in merge sort Although merge-sort runs in Θ(n log n) worst-case time and insertion sort runs in Θ(n 2 ) worst-case time, the constant factors in insertion sort can make it faster in practice for small problem sizes on many machines. Thus, it makes sense to coarsen the leaves of the recursion by using insertion sort within merge sort when subproblems become sufficiently small. Consider a modification to merge sort in which n/k sublists of...
