Answer» INTERNAL static VOID findallsubstring(STRING STR) { for (int i = 0; i &LT; str.Length; ++i) { StringBuilder subString = new StringBuilder(str.Length - i); for (int j = i; j < str.Length; ++j) { subString.Append(str[j]); Console.Write(subString + " "); } } }

3.	Write a program in C# Sharp to find if a given string is palindrome or not?
Answer» INTERNAL static void chkPalindrome(string str) { bool flag = FALSE; for (INT i = 0, j = str.Length - 1; i < str.Length / 2; i++, j--) { if (str[i] != str[j]) { flag = false; break; } ELSE flag = true; } if (flag) { Console.WriteLine("Palindrome"); } else Console.WriteLine("Not Palindrome"); Output: Input: Key Output: Not Palindrome Input: step on no pets Output: Palindrome
