I've made a program that outputs you the most common word in txt file.
And does anybody know how to optimize it that it would work for bigger
files and faster.
The output image: http://i.stack.imgur.com/fVBh0.png
Here is the code.
#include <iostream>
#include <string>
#include <fstream>
#include 
I want to solve the following in Python:
x^101 = 8765 (mod 9691573)
I coded this:
n = 8765
power = 101
mod = 9691573
x = 0
while x < mod:
if (x ** power) % mod == n:
break
x += 1
print x
How can this code be improved for efficiency?
for my first basic project with functions I wanted to make a program that would allow you to input a number, and it would output whether it was prime or not. For the most part, It's functional and working.
I'm quite new to programming so my question is, how can I optimize it to be more efficie...
I attempted to write an O(N) Fibonacci.
fibMemo :: Integer -> Map Integer Integer -> Integer

| n == 1 = 1
| otherwise = case maybeMember of Just x -> x
Nothing -> calced
where maybeMember = M.lookup n map
