一个理发店，只有一个理发师，只有n张可供顾客等待理发的椅子，如果没有顾客，则理发师睡觉；如果有一顾客进入理发店发现理发师在睡觉，则把他叫醒，写一个程序协调理发师和顾客之间的关系。(A barber shop, there is only one barber, only the n Zhang barber' s chair waiting for customers, without customers, the barber to sleep if there is a customer into the barber shop barber was found sleeping, others view him wake up, write a program Coordination between barber and customer relations.)

说明：  计算aic值，主要是用于ar模型算法中测算模型阶数(Aic value calculation, the main model algorithm is used to measure ar model order)

最小二乘窄带干扰消除。有用信号是一个点状目标，产生窄带干扰采样，产生高斯白噪声，设计一个M=100个系数的单步(D=1)线性预测器，再用得到的线性预测器来消除图中被干扰的信号x(n)中的噪声。(Least Squares narrowband interference cancellation. The useful signal is a target point, narrow-band interference is sampled Gaussian white noise, the design of a M = 100 coefficients in a single step (D = 1) linear predictor, then the obtained linear prediction filter to eliminate the interference graph the signal x (n) the noise.)
