Write ONE SQL statement for each of the following tasks. Note that you can only use conditions specified in the task description and cannot manually look up data and add conditions. E. g., in task 1, you cannot manually look up category ID for carpet cleaner. You want to make sure your code will work regardless of what data are in the database (e. g., whether carpet cleaner has a category ID of 1 or 100).Task 1: Return names and emails of authors of the paper titled 'A novel approach of mining EHR data' Task 2: Return reviewer ID, review decision, and review comments of the paper titled 'Comparing big data systems' Task 3: Return paper title and number of authors for each paper. Task 4: Return names of authors who have at least two papers. Task 5: List names of authors who have co-authored with Dr. Chen.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
