Minimum difference between two elements in an array

Problem statement:- Program to Minimum difference between two elements in an array.

Example:-

              Input : Given

                                 size=5

                                 arr[]=[9,1,8,11,13] 

             Output: Minimum difference between two Element is 1 //(9-8=1)            

Data requirement:-

Here is the source code of the C Program to Minimum difference between two elements in an array.

Code:

#include<stdio.h>

#include<limits.h>

#include<math.h>

main()

{

    printf("Enter the size of the array:");

    int size;

    scanf("%d",&size);

    int arr[size];

    int i,j,p;

    printf("Enter the Element of the array:\n");

    for(i=0;i<size;i++)

    {

        scanf("%d",&arr[i]);

    }

    int Min_diff=INT_MAX;

     for(i=0;i<size-1;i++)

    {

         for(j=i+1;j<size;j++)

          {

              if(abs(arr[j]-arr[i])<Min_diff)

              {

                 Min_diff=abs(arr[j]-arr[i]);

              }

          }}

     printf("Minimum difference between two Element is %d",Min_diff);

}

using namespace std;

int main()

{

    cout<<"Enter the size of the array:";

    int size;

    cin>>size;

    int arr[size];

    int i,j;

    cout<<"Enter the Element of the array:\n";

    for(i=0;i<size;i++)

    {

        cin>>arr[i];

    }

    int Min_diff=INT_MAX;

     for(i=0;i<size-1;i++)

    {

         for(j=i+1;j<size;j++)

          {

              if(abs(arr[j]-arr[i])<Min_diff)

              {

                 Min_diff=abs(arr[j]-arr[i]);

              }

          }}

     cout<<"Minimum difference between two Element is "<<Min_diff;

}

Input/Output:

Enter the size of the array:4

Enter the Element of the array:

10 5 3 4

Minimum difference between two Element is 1

Program in Java

Here is the source code of the Java Program to Minimum difference between two elements in an array.

Code:

import java.util.Scanner;

public class MinimumDifference {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

  System.out.println("Enter the size of the array:");

     int size,i,j;

     size=sc.nextInt();

     int arr[ ]=new int[size];

     System.out.println("Enter the Element of the array:");

      for(i=0;i<size;i++)

     {

         arr[i]=sc.nextInt();

     }

     

     int Min_diff=Integer.MAX_VALUE;

     for(i=0;i<size-1;i++)

    {

         for(j=i+1;j<size;j++)

          {

              if(Math.abs(arr[j]-arr[i])<Min_diff)

              {

                 Min_diff=Math.abs(arr[j]-arr[i]);

              }

          }}

     System.out.println("Minimum difference between two Element is "+Min_diff);

   sc.close();

}

}

Input/Output:

Enter the size of the array:

6

Enter the Element of the array:

25 8 31 2 41 51

Minimum difference between two Element is 6

Program in Python

Here is the source code of the Python Program to Minimum difference between two elements in an array.

Code:

import sys

arr=[]

size = int(input("Enter the size of the array: "))

print("Enter the Element of the array:")

for i in range(0,size):

    num = int(input())

    arr.append(num)

Min_diff=sys.maxsize

for i in range(0,size-1):

    for j in range(i+1, size):

        if abs(arr[j]-arr[i])<Min_diff:

            Min_diff = abs(arr[j] - arr[i])
