Example
Input : madam
Output : palindrome
Input : madam
Output : Not a palindrom
Solution:
Step’s
·
First do some
validation
·
Store the string in a
char array
·
Using loop store
reverse string in another string
·
Compare the both
string
public static void Palindrom(string str)
{
if
((str == null) || (str.Length <= 1))
Console.Write(str);
else
{
str = str.ToUpper();
char[] chr = str.ToCharArray();
string str2 = "";
for (int i = chr.Length - 1; i >=
0; i--)
{
str2 += chr[i];
}
if (str.Equals(str2))
{
Console.Write("String " + str + " is palindrom ");
}
else
{
Console.Write("String " + str + " is Not a palindrom
");
}
}
}
static void Main(string[] args)
{
Console.WriteLine("=============================================================================");
Console.WriteLine("How do you check if a given string is a
palindrome?");
Console.WriteLine("=============================================================================");
Program objprog = new Program();
Program.Palindrom("madam");
Console.ReadLine();
}
