Write a program that extracts an odd number of elements from all elements of a given string
Here's a Python program that extracts an odd number of elements from all elements of a given string:
```
def extract_odd_elements(string):
result = []
for element in string:
odd_elements = ''
for i in range(len(element)):
if i % 2 == 0:
odd_elements += element[i]
result.append(odd_elements)
return result
```
This program first defines a function called `extract_odd_elements` that takes a string as input. It then creates an empty list called `result` to store the extracted elements.
For each element in the input string, the program creates a new string called `odd_elements`. It then iterates over the characters in the element using a `for` loop and checks if the index of the character is odd (i.e., divisible by 2). If the index is odd, the character is added to the `odd_elements` string.
After all the characters in the element have been checked, the `odd_elements` string is appended to the `result` list. This process is repeated for all elements in the input string.
Finally, the program returns the `result` list, which contains the odd-numbered elements from all elements of the input string.
java (Replace words) Suppose you have a lot of files in a directory that contain words Exercisei_j, where i and j are digits. Write a program that pads a 0 before i if i is a single digit and 0 before j if j is a single digit. For example, the word Exercise2_1 in a file will be replaced by Exercise02_01. In Java, when you pass the symbol * from the command line, it refers to all files in the directory (see Supplement III.V). Use the following command to run your program: java Exercise12_27 *
Sure, here's the Java code to accomplish the task:
```java
import java.io.File;
public class Exercise12_27 {
public static void main(String[] args) {
String[] files = args;
for (int i = 0; i < files.length; i++) {
if (files[i].startsWith("Exercise")) {
File file = new File(files[i]);
String filename = file.getName();
String[] parts = filename.split("_");
int iValue = Integer.parseInt(parts[0].substring(8));
int jValue = Integer.parseInt(parts[1].substring(0, parts[1].indexOf(".")));
String newFilename = "Exercise" + String.format("%02d", iValue) + "_" + String.format("%02d", jValue) + ".txt";
File newFile = new File(file.getParent(), newFilename);
file.renameTo(newFile);
}
}
}
}
```
This code takes the command line arguments as an array of strings, and loops through each argument. If the argument starts with "Exercise", it creates a `File` object for the file, and extracts the i and j values from the filename using string manipulation. It then creates a new filename with 0-padding for i and j values, and renames the file using the `renameTo()` method of the `File` class. You can run this program by saving it as a .java file and compiling it with `javac filename.java`, and then running it with `java Exercise12_27 *` in the directory with the files.
