Answer:
In Python:
def ret_formatted(num1,num2,num3):
result = str(num1)+"_"+str(num2)+" ! "+str(num3)
return result
Explanation:
This defines the function
def ret_formatted(num1,num2,num3):
This generates the output string
result = str(num1)+"_"+str(num2)+" ! "+str(num3)
This returns the result string
return result

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.
This is true
We can simply put media convergence as the merging of previously distinct media technologies into one core technology or ecosystem. All it takes is separate ideas being smashed together to form one big idea. An example of media convergence is a smartphone. The smartphone is the technological convergence of communication. It can be used to communicate while functioning as a computer on which we share and view content. Before, this could have taken several devices to accomplish the above task individually.
I would say safety. Not putting too much information about yourself on the internet is a good thing to do, because people can follow you (in a bad way). Another thing to think about is not putting information about others if they do not want it on the internet. Also, be careful while you are around computers. You do not want to spill any water on it, or drop it.
