It is necessary to make one from two arrays. Thank you in advance

код:


int n = Convert.ToInt32(Console.ReadLine());
int[] a= new int[n];
Random mal= new Random();
double sum=0;
int count=0;
for (int i = 0; i < n; i++)
{
a = mal.Next(150,200);
Console.Write( a+ " ");
if (a>0)
{
sum = sum + a;
count++;
}
}
Console.WriteLine();
int[] b= new int[n];
Random dev= new Random();
for (int i = 0; i < n; i++)
{
b = dev.Next(145,175);
Console.Write( b[i]+ " ");
if (b[i]>0)
{
sum = sum + b[i];
count++;
}
}
Console.WriteLine();
int max_mal = a[0];
int max_dev = b[0];
for (int i = 0; i < n; i++)
{
if (a[i] > max_mal) max_mal = a[i];
if (b[i] > max_dev) max_dev = b[i];
}
double sred=sum/count;
Console.WriteLine("Средний рост" +sred);
Console.WriteLine("Самые высокие из парней" +max_mal*-1);
Console.WriteLine("Самые высокие из девочек" +max_dev);[/i][/i][/i][/i][/i][/i][/i]
