<h3>What is the difference between group and a topic ?</h3>
<h3>Group</h3>
- You can publish a comment or question to the main community feed or to a group of which you are a member. Members with a common interest can form group within the wider community to form a small community around that topic and group posts will only appear in the feeds of other group members, not in the general community feed.
<h3>Topic</h3>
- Topic work similarly to hashtags. Use the "+" symbol to the left of the Post/Ask button to add a topic (tag) to your post or question so that it can be classified along with other related posts and topics are a way to group posts and queries with similar content, but they don’t bring everyone with the same interest together in one place and this is where the groups come in!
Answer:
import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.print("Input a word: ");
String userinput = input.nextLine();
for(int i =0;i<userinput.length();i+=2) {
System.out.print(userinput.charAt(i));
}
}
}
Explanation:
This line prompts user for input
System.out.print("Input a word: ");
This declares a string variable named userinput and also gets input from the user
String userinput = input.nextLine();
The following iterates through every other character of userinput from the first using iteration variable i and i is incremented by 2
for(int i =0;i<userinput.length();i+=2) {
This prints characters at i-th position
System.out.print(userinput.charAt(i));
