Description: A 16-QAM signal X, whose power is normalized as unity, is transmitted with OFDM over the discrete-time channel model h which has been used in Homework #2 and #3. As depicted in the below figure, the transmitter (TX) is now equipped with an N-point IDFT and the receiver (RX) with an N-point DFT, along with adding cyclic prefix (CP) and removing CP removal, respectively. The complex AWGN n is set with 20 dB SNR. Suppose that N=256 and the length of CP is 64. Assuming the OFDM system works with perfect synchronization. -Generate two pseudo random (PN) sequences for X, each with a length of 256 samples which are taken {+1,-1}, and add them before the 16-QAM data with a proper CP. The OFDM frame is depicted in the following figure. PN1 and PN2 are used for channel estimation now. Suppose the PN patterns are known at RX. Use the least squares (LS) method to estimate the channel by averaging the results obtained individually PN1 and PN2. (When perfoming the DFT window for the received signal at RX, you need to notice that the channel results in a delay of 22 samples.)

Description: flirly 精通数学，经常研究数学问题。对于质数这种问题更是无敌。
对于N个不同的质数P1,P2.....Pn，用这些质数作为项（允许重复），任意组成一个数列，使这个数列的任一连续项的乘积不是完全平方数。
求出这种数列的项数的最大值,flirly想知道这个值的大小，由于结果可能很大，只需要输出对一个给定正整数m取模后的结果即可。你知道这个
结果吗？ -Standard input will contain multiple data sets. Each data set consists two parts.
For the first part, the first line is an integer N, followed by N lines. Each line contains an integer Si(Si<=32768), representing
the power of each monkey.
For the second part, the first line is an integer M (M <= 100,000), meaning there were M times of conflicts. Then, M lines follow,
each line contains two integers x and y, which means the xth monkey has conflict with the yth monkey.
