Closest to Zero

 You have been given an integer array A of size N . You need to print the number with the value closest to zero . If there are multiple elements , print the number with the greater value.

Input Format:

• First Line: An integer N denoting  the size  of the array A.
• Next Line: N  space - separated integers denoting the elements of the array A

Output Format:

Print the value  of the element closest to zero . If there  are multiple candidates, then  print the number  with greater value.

Constraints

1<=N<=100

1<=|Ai|<=100 , where |Ai| denotes the absolute value of Ai

Sample input : 

5

0 2 3 4 5

Sample output :

0

Solution :- 

C# 

using System;

using System.IO;

using System.Linq;

using System.Collections.Generic;

public class HelloWorld

{

static public void Main()

{

String line;

line = Console.ReadLine();

int N = Convert.ToInt32(line);

line = Console.ReadLine();

int[] A = new int[N];

A = line.Split().Select(str => int.Parse(str)).ToArray();

int out_ = homeWork(N, A);

Console.Out.WriteLine(out_);

}

static int homeWork(int N, int[] A)

{

int delta = 0;

int beta = 0;

        Array.Sort(A);

        

        Console.WriteLine(" ");

        

for(int i = 0 ; i< N; i++)

{       

delta = (Math.Abs(A[i])-0);

if(i == 0)

{

beta = A[i];

}

if((delta <= Math.Abs(beta)) && (A[i] >=0) )

{

beta = A[i];

}

            if((delta > Math.Abs(beta)) && (A[i] < 0) )

{

beta = A[i];

}

}

return beta;

}

}
