I need some help on Java. I'm stuck on trying to generate a new string by concatenating the reversed substrings of even indexes and odd indexes separately from a given string. I'm not sure how to figure this out. See example.
Example:
Input: abscacd
Output: dasaccb
Substrings: asad, bcc
Reversed substrings: dasa, ccb.
import java.util.Scanner;
public class ReverseSubStrings {
public static void main(String[] args) {
// reading string from user
Scanner sc = new Scanner(System.in);
System.out.println("Enter String");
String str=sc.nextLine();
String even="";
String odd="";
// looping to get even and odd substrings
for(int i=0;i<str.length();i++){
if(i%2==0)
even=even+str.charAt(i)+"";
else
odd=odd+str.charAt(i)+"";
}
// reversing the sub strings
String rev1=new
StringBuffer(even).reverse().toString();
String rev2=new
StringBuffer(odd).reverse().toString();
System.out.println("Reversed substrings :
"+rev1+","+rev2);
System.out.println("Output : "+rev1+rev2);
}
}

I'm trying to recreate an experiment from class but I'm missing some code. I need an arduino uno program that will ask the user to enter a duty cycle and frequency, and to then generate a square pulse width (0-5V) based on those values.
I need help and I'm stuck on this program. I have to do it in the C language on my Linux system. Can someone help me with this please? I have included my instructions and sample output. Thank you -Initialize 2 arrays within the main method, one with odd numbers and one with even numbers. -In the main method swap the arrays. -Print the arrays before and after the swap. //output should look like the following Before Swap firstArray[0] =...
I'm really stuck I need help. C++ Draw separate flowcharts to solve each of the following problems: Read in 20 numbers and write out how many of them were positive (write out the count, not the actual input numbers). Read in numbers until the user chooses to quit. Write out the smallest of the input values. (Make it so that the user has to enter at least one value) Read in numbers until 10 positive values have been found. Write...

I'm trying to construct this program in C#, I found some similiar problems in Java but as a beginner, its not very easy to follow along with the Java code. Create a Console application named RelativesApp to help you remember your relatives’ birthdays. ·Create a Relative class that includes auto-implemented properties for the relative's name, their relationship to you, and two integers to represent their birthday –month, day. ·Declare an array of at least 12 relative objects. ·Fill the array...
I'm still fairly new to java and I haven't programmed with it in half a year, so I can't for the life of me figure this out even though I know its really simple. I'll paste the 2 classes below so any help is much appreciated. The TODO comments are what I'm supposed to do. public class Main { public static void main(String[] args) { /* * This is for the first part of the lab. */ Planner coursePlan...
Any ideas. I'm stuck and need help A 20Ohm coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 5.0 cm and 1000 turns/meter (see figure below). The current in the solenoid changes as I = b sin (a t), where I is in amperes and t is in seconds. Let a = 120 rad/s and b = 6 A. What is the magnitude of the EMF in the 15-turn coil as a function of time?...
