Solve the following python programming problem given the following code:
def _set_many(self, i, j, x) : 
    'Sets value at each (i, j) to x

        Here (i,j) index major and minor respectively.
        ' 
    (M, N) = self._swap (self.shape) 
    def check_bounds(indices, bound) : 
        idx = indices.max () 
        if (idx >= bound) : 
            raise IndexError (('index (%d) out of range (>= %d)' % (idx, bound))) 
idx = indices.min () 
        if (idx < (- bound)) : 
            raise IndexError (('index (%d) out of range (< -%d)' % (idx, bound))) 
check_bounds (i, M) 
    check_bounds (j, N) 
    i = np.asarray (i, dtype = self.indices.dtype) 
    j = np.asarray (j, dtype = self.indices.dtype) 
    n_samples = len (x) 
    offsets = np.empty (n_samples, dtype = self.indices.dtype) 
    ret = _sparsetools.csr_sample_offsets (M, N, self.indptr, self.indices, n_samples, i, j, offsets) 
    if (ret == 1) : 
        self.sum_duplicates () 
        _sparsetools.csr_sample_offsets (M, N, self.indptr, self.indices, n_samples, N, j, offsets) 
if ((- 1) not in offsets) : 
        self.data [offsets] = x 
        return 
else : 
        warn (('Changing the sparsity structure of a %s_matrix is expensive. lil_matrix is more efficient.' % self.format), SparseEfficiencyWarning) 
        mask = (offsets > (- 1)) 
        self.data [offsets [mask]] = x [mask] 
        mask = (~ mask) 
        i = i [mask] 
        i [(i < 0)] += M 
        j = j [mask] 
        j [(j < 0)] += N 
        self._insert_many (i, j, x [mask])
