    What is wrong with the code from editorial?

        _dp_sum[0]=0
    for i in range(1, len(arr)):
        _dp_sum[i]+=_dp_sum[i-1]
        for j in range(1, i):
            _dp_sum[i]+=_dp_partitial_sums[j][i]
        _dp_sum[i]+=arr[i]*sum(range(2, i+1))
        _dp_sum[i]+=_dp_partitial_sums[i][i]
