Python实现的寻找前5个默尼森数算法示例 本文实例讲述了Python实现的寻找前5个默尼森数算法.分享给大家供大家参考,具体如下: 找前5个默尼森数. 若P是素数且M也是素数,并且满足等式M=2**P-1,则称M为默尼森数.例如,P=5,M=2**P-1=31,5和31都是素数,因此31是默尼森数. python2代码如下: from math import sqrt def isPrime(n): 'judge whether a positive integer is a prim
近期比较忙, 抽空出来5.1开源献礼. 但凡学习音频降噪算法的朋友,肯定看过一个算法. <<语音增强-理论与实践>> 中提及到基于对数的最小均方误差的降噪算法,也就是LogMMSE. 资料见: <<Speech enhancement using a minimum mean-square error log-spectral amplitude estimator.>> -----Ephraim, Y. and Malah, D. (1985) 之前也是
题意:题目大意:有N个点,给出从a点到b点的距离,当然a和b是互相可以抵达的,问从1到n的最短距离 poj2387 Description Bessie is out in the field and wants to get back to the barn to get as much sleep as possible before Farmer John wakes her for the morning milking. Bessie needs her beauty sleep, s
