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.

-4

Invalid

5
5 4 3 2 1

5

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

Number of leaders are 5

    }
    else{
        printf("Invalid");
    }
