C# Sharp Basic Algorithm: Exercise-100 with Solution
Write a C# Sharp program to check a given array of integers and return true if the array contains 10 or 20 twice. The length of the array will be 0, 1, or 2.
Pictorial Presentation:
Sample Solution:-
C# Sharp Code:
using System;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(test(new[] { 12, 20 }));
Console.WriteLine(test(new[] { 20, 20 }));
Console.WriteLine(test(new[] { 10, 10 }));
Console.WriteLine(test(new[] { 10 }));
}
public static bool test(int[] nums)
{
return nums.Length == 2
&& ((nums[0] == 10 && nums[1] == 10)
|| (nums[0] == 20 && nums[1] == 20));
}
}
}
Sample Output:
False True True False

Previous: Write a C# Sharp program to create a new array of integers and length 1 or more. The length of the new array will be double length of the given array and all the elements are 1 except the first element which is equal to the given array.
Next: Write a C# Sharp program to check a given array of integers, length 3 and create a new array. If there is a 5 in the given array immediately followed by a 7 then set 7 to 1.
