What are the Big-Oh and Tilde orders of the following code fragment? The fragment is parametrized on the variable n. Assume that you are measuring the number of swap calls. [10 points] public s tat ic void s o r t (Comparable [ ] a ) { int n = a . l eng th ; for ( int j = 0 ; j < n1; j++) { int z = j ; for ( int i = j +1; i < n ; i++) { i f ( a [ i ] < a [ z ] ) { z = i ; } } i f ( z != j ) { swap ( a [ j ] , a [ z ] ) ; // count t h e s e } } } (a) What is the Big-Oh order of the above code fragment? If it does not exist, then explain. (b) What is the Tilde order of the above code fragment? If it does not exist, then explain.

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() { }
