Here I wrote code for finding repeated
(Duplicate numbers) numbers using lambda expression in c#.
I know its easy but surely it will for beginners.
public
static void
repeated()
{
int count=0;
int[] data = { 1, 2, 3, 4, 5, 6, 7, 8, 5, 9, 8, 10, 11, 12, 10, 13, 14,
15, 12, 16, 17, 18, 15, 19, 20 };
var res = data.GroupBy(t
=> t);
foreach(var
t in res)
{
if (t.Count() > 1)
{
Console.WriteLine("The
number " + t.Key + " repeated " +
t.Count() + " times");
}
}
}
