为什么Haskell中的因子计算要比Java中快得多 我遇到的一个编程问题涉及计算大数(最多10 ^ 5的数字)的阶乘.我见过一个简单的Haskell代码,就像这样 factorial ::(Eq x, Num x)=>x -> x factorial0=1factorial a = a * factorial (a -1) Run Code Online (Sandbox Code Playgroud) ...
Given an integern, return the number of trailing zeroes inn!. Note:Your solution should be in logarithmic time complexity. 解题思路: 计算n能达到的5的最大次幂,算出在这种情况下能提供的5的个数,然后减去之后递归即可,JAVA实现如下: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 staticpubl...
