#include <stdio.h>

int main(){     
    int N, valores[10000], i, j, pontuacao=0;
    scanf("%d", &N);
    for (i=0; i<N; i++){
        scanf("%d", &valores[i]);
       }

    for(i=0; i<N; i++){
     for(j=i+1; j<N; j++){
            if (valores[i] == valores[j])
                pontuacao++;
}
        }
        printf("%d", pontuacao);

    return 0;
}

it suposed to be returning the number of points in a sequence of consecutive numbers, example:
input: 11 (N) 30 30 30 40 40 40 40 40 30 30 30
output: (suposed to be 5) 25??
the strange thing is that it works for other sequences…
