Ans:-
using System;
public class Test
{
public static void Main()
{
String s = "2A3B4C";
String ans = "";
for(int i = 0; i < s.Length;)
{
int num = 0;
while(s[i] >= '0' && s[i] <= '9')
{
num = num * 10 + (s[i] - '0');
i++;
}
while(num-- > 0)
{
ans += s[i];
}
i++;
}
Console.WriteLine(ans);
}
}
2. Check Whether the Entered Number is an Armstrong Number or Not.

{
int number, remainder, sum = 0;
Console.Write("enter the Number");
number = int.Parse(Console.ReadLine());
for (int i = number; i > 0; i = i / 10)
{
remainder = i % 10;
sum = sum + remainder*remainder*remainder;
}
if (sum == number)
{
Console.Write("Entered Number is an Armstrong Number");
}
else
Console.Write("Entered Number is not an Armstrong Number");
Console.ReadLine();
}
