Answer:

The concealment cipher.

Explanation:

A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.

The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.

Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.

mr_godi [17]

Answer:

Meaning:

PT BOAT ONE OWE NINE LOST IN ACTION IN BLACKETT  

STRAIT TWO MILES SW MERESU COVE X CREW OF TWELVE  

X REQUEST ANY INFORMATION.

Explanation:

Playfair cipher  invented in 1854 by Charles Wheatstone was the first practical digraph substitution cipher. Lord Playfair promoted the use of the cipher, therefore it was named after him. Playfair cipher encrypts pairs of letters (digraphs) making it hard to break.  Frequency analysis can still be undertaken but requires much more cipher text in order to work. It requires no additional equipment to operate and is very fast therefore it is to protect information during war. It was used  by British forces in the Second Boer War and in World War I and during World War II by the Australians.  

When the PT-109 American patrol boat, under the command of Lieutenant John F. Kennedy, was sunk by a Japanese destroyer, a message was received at an Australian wireless station in the morning of the 2 of August 1943  in Playfair code:

KXJEY  UREBE  ZWEHE  WRYTU  HEYFS  

KREHE  GOYFI  WTTTU  OLKSY  CAJPO  

BOTEI  ZONTX  BYBWT  GONEY  CUZWR  

GDSON  SXBOU  YWRHE  BAAHY  USEDQ

Meaning:

PT BOAT ONE OWE NINE LOST IN ACTION IN BLACKETT  

STRAIT TWO MILES SW MERESU COVE X CREW OF TWELVE  

X REQUEST ANY INFORMATION.

Explanation:

In Selection Sort algorithm it sorts the array by repeatedly finds the minimum in the array form the array that is unsorted and swaps it with the value at the first position.

The unsorted array:- 5 3 9 5

In first iteration

minimum is 3.

3 will be swapped with 5.

Now the array is 3 5 9 5

sorted array 3

In second iteration

unsorted array is 5 9 5

sorted array 3 5

and the minimum from it is 5

No swapping will occur.

In third iteration

unsorted array is 9 5

minimum is 5

sorted array 3 5 5

swap it with 9.

Now the array is sorted.

3 5 5 9
