Answer: Something people can change and share. It is usually given the bad name of have a bunch of fake information and bugs. Wikipedia is a good example of an open source website but it is not a program.
Explanation: An open source program is a program where you have free rein to basically do whatever you want to it.
The choices are a) credible website B)search log c) Boolean operator d) online database.
The answer is, d. Online database. There are already numerous online digital tools that can aid research. Examples are readcube, mendeley, google scholar. It helps you save and organize researches as well as automatically give bibliographies according to your need like APA and MLA. These tools can hold and save different information that researchers need.
Here is a Python program:
tmp = input().split(' ')
c = tmp[0]; s = tmp[1]
ans=0
for i in range(len(s)):
if s[i] == c: ans+=1
# the ans variable stores the number of occurrences
print(ans)
Answer:
The complete method is as follows:
public List buildList(List L)
{
L.insert(30);
L.insert(23);
L.insert(19);
L.insert(4);
return L;
}
Explanation:
To complete the method, we make use of the insert() function.
This inserts elements of the list into list L. However, we have to start from the last element (i.e. in descending order)
So, the explanation is as follows:
L.insert(30); --- This inserts the last element
Continue inserting in descending order
<em> L.insert(23); </em>
<em> L.insert(19);
</em>
Until the first list element is inserted
L.insert(4);
This returns the filled list L
return L;
Answer:
I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.
Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.
Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.
