- Here we are extensively using string builder class which is mutable, ie editable. In other words it does not create a new copy during the operations as opposed to string class.
- It is a best practice to try with static methods and classes which are not instance specific
- We remember string is array of chars....
static string stringreverse(string input)
{
StringBuilder sb = new StringBuilder();
for (int i = input.Length-1; i >= 0; i--)
{
sb.Append(input[i]);
}
return sb.ToString();
}
