Pow(a, b) counter power Q2.Write a general-purpose function to convert all given year into its roman equivalent. Example Roman equivalent of 1988 is mdcccclxxxviii Roman equivalent of 1525 is mdxxv static subvert Main(string args) Console. WriteLine(enter the year) int number=Convert. ToInt16(Console.

Sqrt(deri) return squ private int average(int f) int avg = f / 5 return avg private int sum(int a, int b, int c, int d, int e) int sum = a + b + c + d + e return sum Q5. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. int sum = 0 for (int i = 3 i 1000 i++) if (i % 3 == 0 i % 5 == 0) sum += i Console. WriteLine(sum. ToString()) Q6. A palindromic number reads the same twain ways.The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 99. Find the largest palindrome made from the product of two 3-digit numbers. int maxPalindrome = 0 for (int i = 100 i 1000 i++) for (int j = i j 1000 j++) int product = i * j if (product. IsPalindrome() && product maxPalindrome) maxPalindrome = product System. Console. WriteLine(maxPalindrome) public static class Extensions public static bool IsPalindrome(this int i) List chars = new List(i. ToString(). ToCharArray()) chars. Reverse() return i == int. Parse(new string(chars. ToArray()))
