mfukar / memoizer.cpp
Created Nov 17, 2015
A generic memoizer class for C++14 functions
View memoizer.cpp
/**
* A memoizer (Y-combinator), with a cache on operator().
*
* The type of the function that can be memoized is (((Args...)->R), Args...) -> R, which
* makes the memoizer of type ( (((Args...) -> R), Args...) -> R ) -> ((Args...) -> R).
*
* WARNING: If the memoized function modifies its arguments, the results will not be
* cached correctly.

Just some random interview question + solution, I don't even remember from where any more
View idontknow.c
/**
* The array contains a set of unsorted numbers. All numbers appear an even number of
* times. The exception is two numbers, call them M and N, which appear an odd number of
* times. Find M and N.
*
* This solution is O(n), where n is the size of the array. It requires two passes over
* the array.
*
* The generalised version of this problem (N elements, one number repeats K times) can
* be reduced to solving the linear system of equations:
