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

Read this excerpt from helen keller’s autobiography, the story of my life. have you ever been at sea in a dense fog, when it seemed as if a tangible white darkness shut you in, and the great ship, tense and anxious, groped her way toward the shore with plummet and sounding-line, and you waited with beating heart for something to happen? i was like that ship before my education began, only i was without compass or sounding-line, and had no way of knowing how near the harbour was. "light! give me light! " was the wordless cry of my soul, and the light of love shone on me in that very hour. . the morning after my teacher came she led me into her room and gave me a doll. the little blind children at the perkins institution had sent it and laura bridgman had dressed it; but i did not know this until afterward. when i had played with it a little while, miss sullivan slowly spelled into my hand the word "d-o-l-l." i was at once interested in this finger play and tried to imitate it. when i finally succeeded in making the letters correctly i was flushed with childish pleasure and pride. running downstairs to my mother i held up my hand and made the letters for doll. i did not know that i was spelling a word or even that words existed; i was simply making my fingers go in monkey-like imitation. in the days that followed i learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. based on this excerpt, which words best describe helen keller?
