Answer:
- def getCharacterForward(char, key):
- charList = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
-
- if(len(char) > 1):
- return None
- elif(not isinstance(key, int)):
- return -1
- else:
- index = charList.find(char)
- if(index + key <= 25):
- return charList[index + key]
- else:
- return charList[(index + key)% 26]
-
- print(getCharacterForward("C", 4))
- print(getCharacterForward("X", 4))
Explanation:
Firstly, define a charList that includes all uppercase alphabets (Line 2). We presume this program will only handle uppercase characters.
Follow the question requirement and define necessary input validation such as checking if the char is a single character (Line 4). We can do the validation by checking if the length of the char is more than 1, if so, this is not a single character and should return None (Line 5). Next, validate the key by using isinstance function to see if this is an integer. If this is not an integer return -1 (Line 6 - 7).
Otherwise, the program will proceed to find the index of char in the charList using find method (Line 9). Next, we can add the key to index and use the result value to get forwarded character from the charList and return it as output (Line 11).
However, we need to deal a situation that the char is found at close end of the charList and the forward key steps will be out of range of alphabet list. For example the char is X and the key is 4, the four steps forward will result in out of range error. To handle this situation, we can move the last two forward steps from the starting point of the charList. So X move forward 4 will become B. We can implement this logic by having index + key modulus by 26 (Line 13).
We can test the function will passing two sample set of arguments (Line 15 - 16) and we shall get the output as follows:
G
B
Answer:
The simple algorithm is described below
Explanation:
assign all men and women as free
while some man m is free do
w = highest ranked women on m's list
if w is free
then m proposes w and m and w are engaged
else if w is not free and with m1
and if w picks m over m1
then w and m are engaged
free m1
end
output all the pairs
Answer:
CSS , (Possibly Divs)
Explanation:
I have picked CSS, and possibly Div's as my main explanation and answer here is why.
CSS - Cascading Style Sheets, this allows you to edit multiple elements in a HTML document, such as the color or any CSS attribute.
If you would like to learn more about CSS, and the multiple options that CSS provides such as Internal Styles, External Styles, lastly In-line styles. I highly recommend the resource "W3Schools".
DIV's - Divs are basically like a container, where you can input styles into this container that can effect those elements such as if I want the background-color, of the div it would effect all the elements inside that div. However, I said this could be a possibility since it isn't CSS where it is styled however you can group these elements to one div. You can also edit the CSS of the Div to effect it.
