After sometimes Mukesh checking the box, he was confused among organic and hybrid apple. He started to count the hybrid apples. Please help to Mukesh Count the total number of hybrid apples in the box.

 #include <stdio.h>

#include<string.h>

int main()

{int numofapples ,x,i,c=0;

scanf("%d",&numofapples);

int arr[100]={0};

for(i=0;i<numofapples;++i){

    scanf("%d",&x);

    arr[x]++;

}

for(i=0;i<100;++i){

    if(arr[i]>1)c+=(arr[i]-1);

    }

printf("%d",c);

return 0;
