the decoding of the following code using the Sardinas-Patterson approach. Show each step. C = {1001, 1011,111,10, 1110}.

the binary sequence of codes

prefix code: No code in a codeword begins with any other code.

Code that can only be cracked once: merely a prefix code or codes that can only be decoded one way

Using the Sardinas-Patterson approach, determine whether a given code is a UDC.

>> Lookup prefix

if identified

Add the dangling suffix to the list of codewords.

If the dangling suffix of a codeword is the same as any other code, the codeword cannot be decoded with absolute certainty.

If there isn't a unique dangling suffix left, it's a prefix code or UDC.

if not discovered

>This is UDC

Let a = "0,10,0110" where 0 is a prefix of 0110 and 110 is the dangling suffix.

provided codeword c = 1001, 1011, 111, 10, 1110.

Here, 111 is the prefix of 1110, while 0 is the dangling suffix.

10 is a prefix of 1001, 1011, and 01, 11 is the dangling suffix.

give the codeword a dangling suffix

=> { 1001, 1011, 111, 10, 1110, 0, 01, 11 }

Here, 0 is the prefix of 01, and 1, is the dangling suffix.

11 precedes 111, and 1 serves as the dangling suffix.

hanging suffix added to codeword

=> { 1001, 1011, 111, 10, 1110, 0, 01, 11, 1, 1}

This codeword was not uniquely decodable because code 1 was repeated throughout.

decoding of codeword c=1001, 1011, 111, 10, and 1110 is hence not unique.

Binary search is a search technique used in computer science that identifies the location of a target value within a sorted array. It is also referred to as half-interval search, logarithmic search, or binary chop. The center member of the array is what the binary search compares the target value to. If not, the half in which the target cannot lie is removed, and the search is then continued on the other half, using the middle element once more to compare to the target value. This process is repeated until the target value is discovered. The target is not in the array if the search yields an empty second half.

It is intended to think of the two binary trees as two subtrees of a heap with its largest member removed.  Choose the best of qualifying. Below you will find the answer.

The two binary trees should be thought of as two subtrees of a heap with its largest member removed.

Algorithm:

Add T1 and T2 as the left and right subtrees to a new binary tree node.

Choose the biggest item from rootT1 and rootT2, then heapify by placing that item in the new root.

If rootT1 or rootT2 was chosen in step 2, then repeat the process for them, and so on, until the heap is recovered.

Complexity:

In O, one can generate a binary tree node (1).

This is completed continuously. O(1)

Since the item chosen to replace the one that was previously in the node we are at is taken from that node's descendants, each step requires constant time, O(1), and we go down the tree one level for each step. As a result, we will take as many steps as the tree's height. It will take O(MaxH1, H2), which is O(H1 + H2) because we don't know if we'll descend into T1 or T2.

Following that, the sum is O(1) + O(1) + O(1)O(H1 + H2) = O(H1 + H2).

Correctness:

For T1 and T2, the heap property is true, i.e., the roots are larger than the items in the corresponding trees. The best of the two roots is chosen as the new root because it is the greatest, The new root will surpass everything in both subtrees.

Then, the parameter can be used again for each stage of the heapify procedure.
