How to find the two largest elements in an array with C#

Answer 1

using System;
  
class Program
{
    static Tuple<int, int> getTheTwoLargest(int[] arr) { 
        int max = Int32.MinValue, secondmax = Int32.MinValue;
     
        for (int i = 0; i < arr.Length; i++) {
            if (arr[i] > max) {
                secondmax = max;
                max = arr[i]; 
            } else if (arr[i] < max && arr[i] > secondmax) {
                secondmax = arr[i]; 
            }
        }
        return Tuple.Create(max, secondmax);
    }
    static void Main() {
        int[] arr = {7, 3, 0, 8, 2, 5, 99, 4, 6};
        var result = getTheTwoLargest(arr);
           
        Console.WriteLine("First Largest: {0}\nSecond Largest: {1}", result.Item1, result.Item2);
    }
}
   
   
       
         
         
/*
run:
         
First Largest: 99
Second Largest: 8
         
*/
