Question

static public int[] Question() // retrieve an integer 'n' from the console // the first input WILL be a valid integer, for 'n' only. // then read in a further 'n' integers into an array. // in the case of bad values, ignore them, and continue reading // values until enough integers have been read. // this question should never print "Bad Input" like in lab // hint: make subfunctions to reduce your code complexity return null; static public int Question7(string s) // s contains a series of possible integers seperated by spaces. // return the sum of all integers. // Example input: // "1 2 3" -> 6 // "1 bob 4" -> 5 return 0; static public int Question(int i) // this function must throw an IndexOutOfRangeException // if i is less than 0 // otherwise return i+3; return 0; static public string Question(string s) //create a function that returns the reverse of the input string // "reverse" -> "esrever" // "salacia" -> "aicalas" // for full credit, this must run "fast" as described in class. // partial credit will be awarded for correct but slow solutions. return null;

Answer 1

static public int Question7(String s) {
    List<int> numbers = new List<int>( Array.ConvertAll(s.Split(','), int.Parse) );
    return numbers.Sum(x => Convert.ToInt32(x));
}

static public int Question8(int i) {
    if (i < 0) {
        throw new IndexOutOfRangeException();
    }
    return i + 3;
}
