Answer:
Hi!
It is not possible to have a deadlock involving only one process.
Explanation:
Deadlock is only possible if there are multiple processes trying to access the same shared resources. Another way to see it is if you have shared resources only can be a deadlock if multiple processes attempt to use it.
With only one process, you can use shared resources without the risk of fall into deadlock, but you don't have concurrence either.
Answer:
A
Explanation:
A common approach to a daily scrum (although not the only approach) is for each member of the development team to address the following three daily scrum questions:
1. What did I accomplish since the last daily scrum?
2. What do I plan to work on by the next daily scrum?
3. What are the obstacles or impediments that are preventing me from making progress?
Development teams are typically between five to nine people. Each development team member should need no more than 90 seconds to address the three questions listed above. So, if you had a team of nine people, each of whom took 90 seconds to cover the questions, combined with some overhead of getting the meeting started and transitioning from person to person, you would end up with a meeting duration of about 15 minutes.
To emphasize that 15 minutes should be thought of as a timeboxed limit.
Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
<h2>A line of code that begins with the "while" needs to end with <u>":"</u> symbol</h2>
Explanation:
In python, the while loop statement has ":" at the end of the line.
<u>Syntax:</u>
while expression:
code(s) or statement(s)
<u>Example:</u>
cnt = 0
while (cnt < 5):
print 'cnt:', cnt
cnt = cnt + 1
Like other programming languages, while loop works in the same way except that in python it comes alone with "else" statement. When the condition is false, "else" statement gets executed.
<u>Example:</u>
#!/usr/bin/python
cnt = 0
while cnt < 5:
print cnt, " is less than 5"
cnt = cnt + 1
else:
print cnt, " is not less than 5"
