设信号 ，用 对x(t)采样得x(n)，是否会发生频谱混叠？现利用FFT分析其频谱。 1．编程绘制该信号的波形。 2．若令N=16，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 3．令N=1024，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 4．分析2、3的运算结果。 设计调试报告要求： 1．工作原理简述； 2．设计思路； 3．难点及解决方法； 4．设计、调试结果及分析； 5．程序文本及操作步骤。(based signal used to x (t) in the sample x (n), whether there will be a spectrum aliasing? FFT analysis is the use of their spectrum. 1. Programming mapping of the signal waveform. 2. If so N = 16, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 3. Order N = 1024, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 4. Analysis of two, three computational results. Design debugging reporting requirements : 1. Principle outlined; 2. Design; 3. Difficulties and solutions; 4. Design, debugging and analysis of results; 5. Text and operating procedures steps.)

今年计算机学院研究生入学复试分多个小组。现在老师需要知道每组复试同学中男生和女生的人数。请你编写程序分别统计出男女生的总人数。 Input 输入的第一行是一个数t(0 < t < 10)，表示有t组测试用例。 对于每组输入数据有两行，第一行是一个正整数n（1 < n < 1000），表示参加该组复试的总人数。接下来一行有n个整数（取值为0或1），0代表男生，1代表女生，整数间由一个空格隔开。 Output 对于每组测试用例，输出一行，由两个数组成，用一个空格隔开，分别表示男生和女生的总人数。 Sample Input 2 2 1 0 7 0 1 0 0 1 1 0 Sample Output 1 1 4 3 (Statistics person)
