# C Programming – HackerRank Solution | Leaders of an array 1 |

### (HackerRank) Write a Modular C Programming code to solve Leaders of an array 1, An element is called a leader if there exists no element greater than it on the RHS.

Given an array, Count leaders of an array. An element is called a leader if there exists no element greater to it on the RHS.

Input Format

First Line contains ‘N’, the number of array elements. The next line contains an ‘N’ array of elements separated by a space

Constraints

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

Output Format

Sample Input 0

```-4
```

Sample Output 0

```Invalid
```

Sample Input 1

```5
5 4 3 2 1
```

Sample Output 1

```5
```

Explanation 1

``````5 is an leader, since there is no element greater to 5 on RHS
4 is an leader, since there is no element greater to 4 on RHS
3 is an leader, since there is no element greater to 3 on RHS
2 is an leader, since there is no element greater to 2 on RHS
1 is an leader, since there is no element greater to 1 on RHS

CODE:

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

int main() {
int n;
scanf("%d",&n);
if(n>0)
{
for(i=0;i<n;i++)
{
scanf("%d",&array[i]);
}
for(i=0;i<n;i++)
{
status=1;
for(j=i+1;j<n;j++)
{
if(array[i]<array[j])
status=0;
}
if(status==1)
}
}
else{
printf("Invalid");
}
}

```
