Answer:
In Python:
def convert_str_to_numeric_list(teststr):
nums = []
res = teststr.split()
for x in res:
if x.isdecimal():
nums.append(int(x))
else:
nums = []
break;
return nums
def get_avg(mylist):
if not len(mylist) == 0:
total = 0
for i in mylist:
total+=i
ave = total/len(mylist)
else:
ave = "None"
return ave
def get_min(mylist):
if not len(mylist) == 0:
minm = min(mylist)
else:
minm = "None"
return minm
def get_max(mylist):
if not len(mylist) == 0:
maxm = max(mylist)
else:
maxm = "None"
return maxm
mystr = input("Enter a string: ")
mylist = convert_str_to_numeric_list(mystr)
print("List: "+str(mylist))
print("Average: "+str(get_avg(mylist)))
print("Minimum: "+str(get_min(mylist)))
print("Maximum: "+str(get_max(mylist)))

Answer:
a. backdoor
backdoor (also called a trapdoor) is a programming routine built into a system by its designer or programmer. It enables the designer or programmer to bypass system security and sneak back into the system later to access programs or files.
B average because he want to estimate how many people were in the meeting
Answer:
a) "Quit"
c) "Q only
Explanation:
Given
<em>String s = "Go"; </em>
<em>while ((!s.equals("q"))&& (!s.equals(""))) {</em>
<em>System.out.println("In loop"); </em>
<em>s = scnr.next();</em>
<em>}</em>
<em />
Required
What input causes another execution
Analyzing the while condition
<em>while ((!s.equals("q"))&& (!s.equals(""))) </em>
<em />
This can be split into:
<em>!s.equals("q")) && (!s.equals(""))</em>
<em />
Meaning
When s is not equal to "q" and when s is not an empty string
<em />
In other words,
the loop will be executed when user input is not "q" and user input is not empty.
So, from the list of given options: The loop both will be executed when:
a) Input is "Quit"
c) Input is Q only
<em>Input of q will terminate the loop, hence b and d are incorrect</em>
<em />
