Write a recursive function called sumover
that has one argument n, which is an
unsigned integer. The function returns a
double value, which is the sum of the reciprocals of
the first n positive integers. (The reciprocal of x is
the fraction 1/x.) For example, sumover(1) returns
1.0 (which is 1/1); sumover(2) returns 1.5 (which
is 1/1 + 1/2); sumover(3) returns approximately
1.833 (which is 1/1 + 1/2 + 1/3). Define
sumover(0) to be zero. Do not use any local variables
in your function.

Implement the recursive function isPal(), which determines whether a string str is a simple palindrome. A simple palindrome is a string consisting entirely of the characters a-z that reads the same forward and backward. For instance, the upcoming are palindromes: dad, level, mom, madamimadam, . Use the following declaration of isPal(): bool isPal (const string& str, int startIndex, int endIndex); It returns true when the substring in the index range [startIndex, endIndex) is a palindrome. The conditions are Stopping Condition: Result is true when startIndex >= endIndex -1 Result is false when str[startIndex] != str[endIndex-1] Recursive Step: Determine whether the substring of the str in the index range [startIndex+1, endIndex-1] is a palindrome

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() { }
