Sample Solution:
C# Sharp Code:
using System;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(test(new[] { 3, 5, 5, 3, 7 }));
Console.WriteLine(test(new[] { 3, 5, 5, 4, 1, 5, 7}));
Console.WriteLine(test(new[] { 3, 5, 5, 5, 5, 5}));
Console.WriteLine(test(new[] { 2, 4, 5, 5, 6, 7, 5}));
}
static bool test(int[] numbers)
{
int arr_len = numbers.Length;
bool flag = true;
for (int i = 0; i < arr_len; i++)
{
if (numbers[i] == 5)
{
if ((i > 0 && numbers[i - 1] == 5) || (i < arr_len - 1 && numbers[i + 1] == 5)) flag = true;
else if (i == arr_len - 1) flag = false;
else return false;
}
}
return flag;
}
}
}
Sample Output:
True False True False
