The smart Java developer would know when to stop. Life is too short to build castles in the clouds. He’d know that a simple looped solution is more than sufficient, and of course he handles negative numbers. (

我不用猜就知道你的for(factorial=1;number>1;factorial=factorial*number--)这句后面没加“;”,所以你的printf("%d",factorial);成了循环体,然后就是执行顺序了.先。 。 sumoffactorialsfunction阶乘函数的总和sumoffactorialsfunction阶乘函数的总和 。
We may be asked to write a program tocalculate factorialduring coding exercises inJava interviews. This always better to have an idea of how to build such a factorial program. 1. What is Factorial? The factorial of a number is theproduct of all positive descending integersup to1. Factorial...

. They noticed that this function never decreases. If we have two numbers N1<N2, then Z(N1) <= Z(N2). It is because we can never "lose" any trailing zero by multiplying by any positive number. We can only get new and new zeros. The function Z is very interesting, so we need ...
Given an integern, return the number of trailing zeroes inn!. Note: Your solution should be in logarithmic time complexity. 分析 Note中提示让用对数的时间复杂度求解,那么如果粗暴的算出N的阶乘然后看末尾0的个数是不可能的。 所以仔细分析,N! = 1 * 2 * 3 * ... * N 而末尾0的个数只与这些...
