Answer:
Python Code:
def validate_url(url):
#Creating the list of valid protocols and file name extensions
valid_protocols = ['http', 'https', 'ftp']
valid_fileinfo = ['.html', '.csv', '.docx']
#splitting the url into two parts
url_split = url.split('://')
isProtocolValid = False
isFileValid = False
#iterating over the valid protocols and file names for validity
for x in valid_protocols:
if x in url_split[0]:
isProtocolValid = True
break
for x in valid_fileinfo:
if x in url_split[1]:
isFileValid = True
break
#Returning the result if the URL has both valid protocol and file extension
return (isProtocolValid and isFileValid)
url = input("Enter an URL: ")
print(validate_url(url))

Answer:
public class GetInfo{
Beverage[] beverages=new Beverage[100];
int i=0;
GetInfo(Beverage b){
beverages[i]=b;
i++;
}
public void Display(){
for(int i=0;i<beverages.length;i++)
cout<<beverage[i].tostring();
}

Answer:
Ctrl+Space is the keyboard shortcut to select an entire column.
Explanation:
When you press the Shift+Space shortcut the first time it will select the entire row within the Table. Press Shift+Space a second time and it will select the entire row in the worksheet.
The same works for columns. Ctrl+Space will select the column of data in the Table. Pressing the keyboard shortcut a second time will include the column header of the Table in the selection. Pressing Ctrl+Space a third time will select the entire column in the worksheet.
You can select multiple rows or columns by holding Shift and pressing the Arrow Keys multiple times.
Equality and Relational Operators
For the statement to return false, you can simply use the "not equal to" equality operation. The full symbol of this operation is '!=', disregarding the quotes.
<u>Examples:</u>
- [1 != 1] would produce FALSE. Translation: 1 <u>does not equal</u> 1?
- [1 == 1] would produce TRUE. Translation: 1 <u>does</u> 1?
- ["G" != "G] would produce <u>FALSE</u>. Translation: "G" <u>does not equal</u> "G"?
CONCLUSION: Use "!=".
