[数据结构] Shannon

Shannon编码步骤: 1、将信源符号按概率从大到小的顺序排列,     p(a1)≥ p(a2)≥…≥ p(an) 2、确定满足下列不等式的整数Ki, -log2 p(ai) ≤ Ki < 1-log2 p(ai) 3、令P(a1)=0,用Pi表示第i个码字的累加概率, Pi=sum_{k=1}^{i-1} p(ak) 4、将Pi用二进制表示,并取小数点后Ki位作为符号ai的编码。
Shannon coding steps: 1. The source symbols are arranged in order of probability from large to small 2. Determine the integer ki satisfying the following inequality 3. Let P(A1)= 0, and PI denotes the cumulative probability of the i-th codeword, 4. PI is represented in binary system,and Ki bit after decimal point is taken as the code of symbol AI.

[数据结构] shoping

由于换季,ACM商场推出优惠活动,以超低价格出售若干种商品。但是,商场为避免过分亏本,规定某些商品不能同时购买,而且每种超低价商品只能买一件。身为顾客的你想获得最大的实惠,也就是争取节省最多的钱。经过仔细研究过,我们发现,商场出售的超低价商品中,不存在以下这种情况: N(3<=n)种商品C1,C2,…,Cn,其中Ci和Ci+1是不能同时购买的(i=1,2,…,n-1),而且C1和Cn也不能同时购买。 请编程计算可以节省的最大金额数。
