How to find two numbers from an array that are just smaller and just greater than N in C#

Answer 1

using System;

public class Program
{
	public static void Main() {
		int[] arr = new int[] {3, 8, 1, 9, 4, 10, 7, 13, 2, 6};
		int size = arr.Length;
		int N = 4;

		int just_greater = int.MaxValue;
		int just_smaller = int.MinValue;

		for (int i = 0; i < size; i++) {
			if (arr[i] > N && arr[i] < just_greater) {
				just_greater = arr[i];
			}

			if (arr[i] < N && just_smaller < arr[i]) {
				just_smaller = arr[i];
			}
		}

		Console.WriteLine("just_smaller: " + just_smaller);
		Console.WriteLine("N: " + N);
		Console.WriteLine("just_greater: " + just_greater);
	}
}




/*
run:
  
just_smaller: 3
N: 4
just_greater: 6
