费诺编码输入为+7个信源符号,其概率分布为：(其中信源符号用A+B、、G表示)A_0.2++B_0.19++C_0.18++D_0.17++E_0.15++F_0.10++G_0.01然后输入程序中得到结果（详细文档，值得一下）-Fenno+7 encoding of input source symbols, the probability distribution as follows: (in which source symbols with A+ B,, G said) A_0.2++ B_0.19++ C_0.18++ D_0.17++ E_0.15++ F_0.10++ G_0.01 then enter the outcome of proceedings (detailed documentation, it is worth clicking)
