Recursion seems to be one of the solutions, once you have a blueprint

Why ? Lol

Yeah i normal get the same issues in other challenges

public static int FindLongest(int[] number)
{
int longestnum = 0;
foreach(int a in number)
{
longestnum = number.Max();
}
return longestnum;
}
// In your question, you are looking for the value with have the greatest value above all numbers in array.
But what you kept was the answer when testing, was incorrect,
such as 2,983,758 have a great value than [(2,268,174)-->
this would display] as correct answer even though 2,983,758
is greater than 2,268,174.
