球赛门票的售票处规定每位购票者限购一张门票，且每张门票售价 50元。购票者中有 m位手持50元钱币，另有n人手持100元。假设售票处开始售票时无零钱。问这m+n人有 几种排队方式可使售票处不致出现找不出钱的局面。(The box office ticket sales are limited to the provisions of each ticket purchase a ticket, and the price of 50 yuan per ticket. Ticket-holders have m-bit hand-held 50 coins, and another n armed with 100 yuan. Suppose no small change when the ticket office began selling tickets. M+ n asking a few people queuing up outside ticket office can not find the money to avoid a situation.)

一个FFT改进版程序，使用kaiser窗；可以方便地打出信号的频谱包络，以及算出SNR/SINAD/THD/SFDR等各种数值。工程上使用非常便利(FFT with Kaiser Wndw, easily plot out the Frequent spetrum and the SNR/SINAD/THD/SFDR performance values)
