Answer 1

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{

string a;
string b;
a = Console.ReadLine();
// captures input in a

b = "";
// initialise string otherwise += does not work

for(int i=a.Length-1; i>=0; i--)
// sizeof used for type memory not string length. Use the length attribute instead. Arrays start at 0 so last element is one less than length.

{

b+=a[i];
}

Console.Write(b);
}
}
}
