I am trying to compare numbers that are so large that even BigIntegers cannot deal with them. My solution is to convert the numbers to Strings and use String comparison on them.
I\'m attempting to write a function that calculates the number of unique permutations of a string. For example aaa would return 1 and abc would return 6.
I coded 3 factorial algorithms: I expect to fail by stack overflow. No problem. I try a tail recursive call, and convert the previous algorithm from r开发者_开发技巧ecursive to iterative. It doesn\'
Can a working factorial function/operator be defined with a syntax like in mathematics?i.e. using the ! symbol.
I want to calculate the sum of digits of N!. I want to do this fo开发者_运维问答r really large values of N, say N(1500). I am not using .NET 4.0. I cannot use the BigInteger class to solve this.
This is a rather theoretical question, so while the language is specifically Java, any general solution will suffice.
Ive tried to create my own implementation of a bignum library I cant seem to get the factorial to work. If I ask it to solve 4!,it gives out 96. It multiplies 4 twice. similarly, 5! is 600, not 120. I
Here is what i wrote: 开发者_高级运维number = raw_input(\'Enter an integer= \') if number < 0:
I have used many recursive functions now but still have trouble getting my hea开发者_运维百科d around how such a function exactly works (i\'m familiar with the second line (i.e. | n==0 = 1) but am not
Can someone ple开发者_如何学Pythonase explain it to me? I wrote a function to calculate the factorial of a number like this in C#:
