# C Programming – HackerRank Solution | Duplicates 1 |

### Write a Modular C Programming code to solve Duplicates 1, Given an array of integers find the duplicates in it

Given an array of integers find the duplicates in it.

Input Format

First line contains N, number of array elements. Next line contains N array elements separated by a space.

Constraints

N<=10^4 0<=a[i]<=10^9

Output Format

Display Dupliactes separated by a space

Sample Input 0

```5
10 20 10 20 10
```

Sample Output 0

```10 20
```

Sample Input 1

```-5
```

Sample Output 1

```Invalid
```

Sample Input 2

```5
10 20 30 40 50
```

Sample Output 2

`No Duplicate`

CODE:

```#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>

void read_a(int a[30],int n)
{
int i;
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
}

void display_a(int a[30],int n)
{
int i,j,count=0;
int b[30];
for(i=0;i<n;i++)
{
for(j=i+1;j<n;j++)
{
if(a[i]==a[j])
{
b[i]=a[i];
a[j]=0;
count++;
}
}

}
if(count==0)
{
printf("No Duplicate");
exit(0);
}
for(i=0;i<n;i++)
{
if(b[i]!=0)
{
printf("%d ",b[i]);
}

}
}

int main() {
int n,a[30];
scanf("%d",&n);
if(n<1||n>10000)
{
printf("Invalid");
exit(0);
}
display_a(a,n);
return 0;
}
```
