给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)

通过传统互相关的方法来进行声源定位的程序,最后实现延迟差的估计(Estimated by the traditional method of cross-correlation to the sound source localization process, the final realization of the delay difference)

This paper presents an improved maximum power point tracking (MPPT) algorithm of a PV system under real climatic conditions. The proposed MPPT is based on the perturbation and observation (P&O) strategy and the variable step method that control the load voltage to ensure optimal operating points of a PV system.
