Algorithm 1: Split-Range 1
1:	Input:b.list    % the sequence number set of intervals
	b[low/high, length(b.list)] % boundary of intervals
2:	Description:
	bd[low/high, m, K] % the boundary matrix of the sub-intervals
	bp[m, K] % the representative value matrix of the sub-intervals
3:	diff←(b[high] − b[low])/K
4:	fori←0:K − 1 do
5:	bd[low, b.list, i]←i⋅diff + b[low]
6:	bd[high, b.list, i]←(i + 1)⋅diff + b[low]
7:	end for
8:	bp[b.list, 0:K − 1]←round((bd[high] − bd[low])/2)
	% The round function performs rounding to the nearest precision
9:	Output:bp, bd
