元素猜拳：均匀出招也会被看穿？Element Duel: Can a Balanced Pattern Still Be Predicted?
计算出招频率与一阶转移次数，给出预测和反制动作，并分别记录预测正确率与对局胜率。Count frequencies and one-step transitions, make a prediction and counter, and record prediction accuracy separately from game wins.
先在纸上猜结果，再按按钮检验。Predict on paper before checking with the buttons.
课堂版不把猜中加分混入胜率；原项目部分读心关有预测奖励分。这里只实现频率与一阶条件计数，不把它称为神经网络，也不声称能识破所有确定性程序。The classroom version keeps prediction counts separate from wins; some original reading levels award prediction bonuses. This lab implements frequency and first-order conditional counting, not a neural network or a predictor of every deterministic program.
